[Bug 26568] Nothing stopping mis-nested fullscreen in iframes?

https://www.w3.org/Bugs/Public/show_bug.cgi?id=26568

--- Comment #6 from Philip Jägenstedt <philipj@opera.com> ---
Yeah, that looks promising. A case I forgot about is when the relevant iframe
element is already fullscreen, in which case the element ready check would
fail, but that iframe's document's fullscreen element stack isn't supposed to
change.

So I guess one should walk the ancestor iframes, doing the ready check for
them, and stop at the first one (if any) that's at the top of its document's
fullscreen element stack?

This stuff is complicated :(
