Created attachment 298774 [details] Simple repro case If a document's body is fullscreen, a child iFrame can't go fullscreen (even though it has the correct allowfullscreen/webkitallowfullscreen attributes). This seems to contradict the WHATWG fullscreen API as any descendant element should be able to go fullscreen if a parent element is already fullscreen. This is works as intended in both Chrome and Firefox.

I can confirm the issue with the repro case. The parent element remains fullscreen when we try to fullscreen the child. However, I don't see any fullscreenerror message.
