Reviewed by Eric Carlson.

A muted media element will be suspended for InvisibleAutoplay if it ever made hidden.
While playback will resume if the media element is made visible, it should also resum if the media element stays hidden but is unmuted.
To do this, we call scheduleUpdateShouldAutoplay whenever the media element muted state changes.

This also has the effect that a hidden media element that gets muted will also be paused, until it either gets unmuted or made visible again.
