I agree, the spec should definitely allow this. We could make
requestFullScreen()'s entire body run in a synchronous section, after
any permission has been granted?

If you have the fullscreen element as a generic container (div), you can
insert your desired "fullscreen element" as the only child of the actual
fullscreen element to get the swap effect. This won't work cross origin,
so would prevent (for example) embedded YouTube videos from going
fullscreen. I'd prefer for requestFullscreen() while fullscreen to just
swap the fullscreen element.
However, if we do end up not having requestFullscreen() while fullscreen
swap the fullscreen element, then we need to ensure
document.fullscreenEnabled returns false while any document is
fullscreen. Otherwise <video> controls won't know to hide their
(non-functioning) fullscreen buttons while their
document/parent/ancestor documents are fullscreen.
