Yeah, I suggest that if requestFullScreen() is called when another
element is already the fullscreen element, the new requestee should
become the fullscreen element.
A use case for this is: a fullscreen page with a cross-domain <video>
and the <video> wants to go fullscreen. For example if a
slide-deck/PowerPoint clone webapp goes fullscreen and wants to make an
embedded YouTube video fullscreen. The easiest way to do this is load
the YouTube video in an embedded iframe and (assuming you're using their
HTML5 player and that uses the fullscreen API) click on the fullscreen
button in its controls UI.
As I explained on IRC this use case does not work well.
Site A embeds site B. Site A goes fullscreen. Site B does
requestFullscreen(). Site B does exitFullscreen(). Site A is no longer
fullscreen.
Either we need to base fullscreen on browsing contexts rather than
top-level browsing contexts (how?) or give up on this use case.
