MediaControllerLimited availability

The playback of multiple <video> or <audio> elements can be coordinated by a MediaController instance, for example to synchronize a sign-language interpreter track with the main video track.

Not yet supported in all major browsers — check the table and provide a fallback.

Discouraged: The MediaController API was dropped from the specification due to lack of implementations.
