What I meant was to make play() throw if .ownerDocument isn't active,
and make elements pause() when the .owernDocument goes inactive. In that
case it shouldn't be possible to never stop playing.
I agree that it might be desirable to put the <video> in play-mode
without actually starting to play it, so the current text looks fine.
