http://fullscreen.spec.whatwg.org/#:fullscreen-pseudo-class

If an element at the top of its node document's fullscreen element stack is
moved to another document, does the :fullscreen pseudo-class still apply until
the old document's fullscreen element stack is updated in exitFullscreen()?

If yes, it becomes a bit harder to implement :fullscreen, one would have to
have a flag per element instead of checking the the element's node document's
fullscreen element stack. Do not like.

If no, scripts will immediately observe the change in
element.matches(':fullscreen') but the change in oldDocument.fullscreenElement
will be async. That's a bit weird, but maybe OK.
