-     * - Hidden elements have a width of 0 with `window.getComputedStyle`. This function
-     *   defaults to the `Component`s `style.width` and falls back to `window.getComputedStyle`.

-     * back on. We also don't want to completely block touch events from bubbling up.

-   * Primary timing in VHS goes by video. This is different from most media players, as
-   * audio is more often used as the primary timing source. For the foreseeable future, VHS
-   * will continue to use video as the primary timing source, due to the current logic and
-   * expectations built around it.
-
-   * Since the timing follows video, in order to maintain sync, the video loader is
-   * responsible for setting both audio and video source buffer timestamp offsets.
-   *
-   * Setting different values for audio and video source buffers could lead to
-   * desyncing. The following examples demonstrate some of the situations where this
-   * distinction is important. Note that all of these cases involve demuxed content. When
-   * content is muxed, the audio and video are packaged together, therefore syncing
-   * separate media playlists is not an issue.
-   *
-   * CASE 1: Audio prepares to load a new timeline before video:
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:                     ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader              ^
-   *
-   * In the above example, the audio loader is preparing to load the 6th segment, the first
-   * after a discontinuity, while the video loader is still loading the 5th segment, before
-   * the discontinuity.
-   *
-   * If the audio loader goes ahead and loads and appends the 6th segment before the video
-   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
-   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
-   * the audio loader must provide the audioAppendStart value to trim the content in the
-   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
-   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
-   * segment until that value is provided.
-   *
-   * CASE 2: Video prepares to load a new timeline before audio:
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:             ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader                      ^
-   *
-   * In the above example, the video loader is preparing to load the 6th segment, the first
-   * after a discontinuity, while the audio loader is still loading the 5th segment, before
-   * the discontinuity.
-   *
-   * If the video loader goes ahead and loads and appends the 6th segment, then once the
-   * segment is loaded and processed, both the video and audio timestamp offsets will be
-   * set, since video is used as the primary timing source. This is to ensure content lines
-   * up appropriately, as any modifications to the video timing are reflected by audio when
-   * the video loader sets the audio and video timestamp offsets to the same value. However,
-   * setting the timestamp offset for audio before audio has had a chance to change
-   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
-   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
-   *
-   * CASE 3: When seeking, audio prepares to load a new timeline before video
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:           ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader            ^
-   *
-   * In the above example, both audio and video loaders are loading segments from timeline
-   * 0, but imagine that the seek originated from timeline 1.
-   *
-   * When seeking to a new timeline, the timestamp offset will be set based on the expected
-   * segment start of the loaded video segment. In order to maintain sync, the audio loader
-   * must wait for the video loader to load its segment and update both the audio and video
-   * timestamp offsets before it may load and append its own segment. This is the case
-   * whether the seek results in a mismatched segment request (e.g., the audio loader
-   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
-   * loaders choose to load the same segment index from each playlist, as the segments may
-   * not be aligned perfectly, even for matching segment indexes.

-   * Primary timing in VHS goes by video. This is different from most media players, as
-   * audio is more often used as the primary timing source. For the foreseeable future, VHS
-   * will continue to use video as the primary timing source, due to the current logic and
-   * expectations built around it.
-
-   * Since the timing follows video, in order to maintain sync, the video loader is
-   * responsible for setting both audio and video source buffer timestamp offsets.
-   *
-   * Setting different values for audio and video source buffers could lead to
-   * desyncing. The following examples demonstrate some of the situations where this
-   * distinction is important. Note that all of these cases involve demuxed content. When
-   * content is muxed, the audio and video are packaged together, therefore syncing
-   * separate media playlists is not an issue.
-   *
-   * CASE 1: Audio prepares to load a new timeline before video:
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:                     ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader              ^
-   *
-   * In the above example, the audio loader is preparing to load the 6th segment, the first
-   * after a discontinuity, while the video loader is still loading the 5th segment, before
-   * the discontinuity.
-   *
-   * If the audio loader goes ahead and loads and appends the 6th segment before the video
-   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
-   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
-   * the audio loader must provide the audioAppendStart value to trim the content in the
-   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
-   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
-   * segment until that value is provided.
-   *
-   * CASE 2: Video prepares to load a new timeline before audio:
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:             ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader                      ^
-   *
-   * In the above example, the video loader is preparing to load the 6th segment, the first
-   * after a discontinuity, while the audio loader is still loading the 5th segment, before
-   * the discontinuity.
-   *
-   * If the video loader goes ahead and loads and appends the 6th segment, then once the
-   * segment is loaded and processed, both the video and audio timestamp offsets will be
-   * set, since video is used as the primary timing source. This is to ensure content lines
-   * up appropriately, as any modifications to the video timing are reflected by audio when
-   * the video loader sets the audio and video timestamp offsets to the same value. However,
-   * setting the timestamp offset for audio before audio has had a chance to change
-   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
-   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
-   *
-   * CASE 3: When seeking, audio prepares to load a new timeline before video
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:           ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader            ^
-   *
-   * In the above example, both audio and video loaders are loading segments from timeline
-   * 0, but imagine that the seek originated from timeline 1.
-   *
-   * When seeking to a new timeline, the timestamp offset will be set based on the expected
-   * segment start of the loaded video segment. In order to maintain sync, the audio loader
-   * must wait for the video loader to load its segment and update both the audio and video
-   * timestamp offsets before it may load and append its own segment. This is the case
-   * whether the seek results in a mismatched segment request (e.g., the audio loader
-   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
-   * loaders choose to load the same segment index from each playlist, as the segments may
-   * not be aligned perfectly, even for matching segment indexes.

- * In the above example, the audio loader is preparing to load the 6th segment, the first
- * after a discontinuity, while the video loader is still loading the 5th segment, before
- * the discontinuity.
- *
- * If the audio loader goes ahead and loads and appends the 6th segment before the video
- * loader crosses the discontinuity, then when appended, the 6th audio segment will use
- * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
- * the audio loader must provide the audioAppendStart value to trim the content in the
- * transmuxer, and that value relies on the audio timestamp offset. Since the audio
- * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
- * segment until that value is provided.
- *
- * CASE 2: Video prepares to load a new timeline before audio:
- *
- * Timeline:       0                 1
- * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Audio Loader:             ^
- * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Video Loader                      ^
- *
- * In the above example, the video loader is preparing to load the 6th segment, the first
- * after a discontinuity, while the audio loader is still loading the 5th segment, before
- * the discontinuity.
- *
- * If the video loader goes ahead and loads and appends the 6th segment, then once the
- * segment is loaded and processed, both the video and audio timestamp offsets will be
- * set, since video is used as the primary timing source. This is to ensure content lines
- * up appropriately, as any modifications to the video timing are reflected by audio when
- * the video loader sets the audio and video timestamp offsets to the same value. However,
- * setting the timestamp offset for audio before audio has had a chance to change
- * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
- * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
- *
- * CASE 3: When seeking, audio prepares to load a new timeline before video
- *
- * Timeline:       0                 1
- * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Audio Loader:           ^
- * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Video Loader            ^
- *
- * In the above example, both audio and video loaders are loading segments from timeline
- * 0, but imagine that the seek originated from timeline 1.
- *
- * When seeking to a new timeline, the timestamp offset will be set based on the expected
- * segment start of the loaded video segment. In order to maintain sync, the audio loader
- * must wait for the video loader to load its segment and update both the audio and video
- * timestamp offsets before it may load and append its own segment. This is the case
- * whether the seek results in a mismatched segment request (e.g., the audio loader
- * chooses to load segment 3 and the video loader chooses to load segment 4) or the
- * loaders choose to load the same segment index from each playlist, as the segments may
- * not be aligned perfectly, even for matching segment indexes.

- * Returns whether or not the loader should wait for a timeline change from the timeline
- * change controller before processing the segment.
- *
- * Primary timing in VHS goes by video. This is different from most media players, as
- * audio is more often used as the primary timing source. For the foreseeable future, VHS
- * will continue to use video as the primary timing source, due to the current logic and
- * expectations built around it.
-
- * Since the timing follows video, in order to maintain sync, the video loader is
- * responsible for setting both audio and video source buffer timestamp offsets.
- *
- * Setting different values for audio and video source buffers could lead to
- * desyncing. The following examples demonstrate some of the situations where this
- * distinction is important. Note that all of these cases involve demuxed content. When
- * content is muxed, the audio and video are packaged together, therefore syncing
- * separate media playlists is not an issue.
- *
- * CASE 1: Audio prepares to load a new timeline before video:
- *
- * Timeline:       0                 1
- * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Audio Loader:                     ^
- * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Video Loader              ^
- *
- * In the above example, the audio loader is preparing to load the 6th segment, the first
- * after a discontinuity, while the video loader is still loading the 5th segment, before
- * the discontinuity.
- *
- * If the audio loader goes ahead and loads and appends the 6th segment before the video
- * loader crosses the discontinuity, then when appended, the 6th audio segment will use
- * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
- * the audio loader must provide the audioAppendStart value to trim the content in the
- * transmuxer, and that value relies on the audio timestamp offset. Since the audio
- * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
- * segment until that value is provided.
- *
- * CASE 2: Video prepares to load a new timeline before audio:
- *
- * Timeline:       0                 1
- * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Audio Loader:             ^
- * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Video Loader                      ^
- *
- * In the above example, the video loader is preparing to load the 6th segment, the first
- * after a discontinuity, while the audio loader is still loading the 5th segment, before
- * the discontinuity.
- *
- * If the video loader goes ahead and loads and appends the 6th segment, then once the
- * segment is loaded and processed, both the video and audio timestamp offsets will be
- * set, since video is used as the primary timing source. This is to ensure content lines
- * up appropriately, as any modifications to the video timing are reflected by audio when
- * the video loader sets the audio and video timestamp offsets to the same value. However,
- * setting the timestamp offset for audio before audio has had a chance to change
- * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
- * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
- *
- * CASE 3: When seeking, audio prepares to load a new timeline before video
- *
- * Timeline:       0                 1
- * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Audio Loader:           ^
- * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
- * Video Loader            ^
- *
- * In the above example, both audio and video loaders are loading segments from timeline
- * 0, but imagine that the seek originated from timeline 1.
- *
- * When seeking to a new timeline, the timestamp offset will be set based on the expected
- * segment start of the loaded video segment. In order to maintain sync, the audio loader
- * must wait for the video loader to load its segment and update both the audio and video
- * timestamp offsets before it may load and append its own segment. This is the case
- * whether the seek results in a mismatched segment request (e.g., the audio loader
- * chooses to load segment 3 and the video loader chooses to load segment 4) or the
- * loaders choose to load the same segment index from each playlist, as the segments may
- * not be aligned perfectly, even for matching segment indexes.

-   * Primary timing in VHS goes by video. This is different from most media players, as
-   * audio is more often used as the primary timing source. For the foreseeable future, VHS
-   * will continue to use video as the primary timing source, due to the current logic and
-   * expectations built around it.
-
-   * Since the timing follows video, in order to maintain sync, the video loader is
-   * responsible for setting both audio and video source buffer timestamp offsets.
-   *
-   * Setting different values for audio and video source buffers could lead to
-   * desyncing. The following examples demonstrate some of the situations where this
-   * distinction is important. Note that all of these cases involve demuxed content. When
-   * content is muxed, the audio and video are packaged together, therefore syncing
-   * separate media playlists is not an issue.
-   *
-   * CASE 1: Audio prepares to load a new timeline before video:
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:                     ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader              ^
-   *
-   * In the above example, the audio loader is preparing to load the 6th segment, the first
-   * after a discontinuity, while the video loader is still loading the 5th segment, before
-   * the discontinuity.
-   *
-   * If the audio loader goes ahead and loads and appends the 6th segment before the video
-   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
-   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
-   * the audio loader must provide the audioAppendStart value to trim the content in the
-   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
-   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
-   * segment until that value is provided.
-   *
-   * CASE 2: Video prepares to load a new timeline before audio:
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:             ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader                      ^
-   *
-   * In the above example, the video loader is preparing to load the 6th segment, the first
-   * after a discontinuity, while the audio loader is still loading the 5th segment, before
-   * the discontinuity.
-   *
-   * If the video loader goes ahead and loads and appends the 6th segment, then once the
-   * segment is loaded and processed, both the video and audio timestamp offsets will be
-   * set, since video is used as the primary timing source. This is to ensure content lines
-   * up appropriately, as any modifications to the video timing are reflected by audio when
-   * the video loader sets the audio and video timestamp offsets to the same value. However,
-   * setting the timestamp offset for audio before audio has had a chance to change
-   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
-   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
-   *
-   * CASE 3: When seeking, audio prepares to load a new timeline before video
-   *
-   * Timeline:       0                 1
-   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Audio Loader:           ^
-   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
-   * Video Loader            ^
-   *
-   * In the above example, both audio and video loaders are loading segments from timeline
-   * 0, but imagine that the seek originated from timeline 1.
-   *
-   * When seeking to a new timeline, the timestamp offset will be set based on the expected
-   * segment start of the loaded video segment. In order to maintain sync, the audio loader
-   * must wait for the video loader to load its segment and update both the audio and video
-   * timestamp offsets before it may load and append its own segment. This is the case
-   * whether the seek results in a mismatched segment request (e.g., the audio loader
-   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
-   * loaders choose to load the same segment index from each playlist, as the segments may
-   * not be aligned perfectly, even for matching segment indexes.
