It'd be nice if native <video> fullscreen buttons could be implemented using
the fullscreen API directly.  A really nice side-effect would be that
scripted video controls could behave exactly the same as native controls
(possibly excluding permission checks), including document.fullscreenElement
and the fullscreenchanged event.

It seems like it would need fullscreenElement to be a stack, though, so
exitFullscreen can drop back into the previous fullscreen state.
