I have a hard time deciding what would make most sense, but in any case the handling of background will change from :-webkit-full-screen { background-color: white; } video:-webkit-full-screen, audio:-webkit-full-screen { background-color: transparent !important; } to just :not(:root):-webkit-full-screen::backdrop { background: black; } So in a lot of cases it will go from white to black, and this is such a case. It's just that the ::backdrop pseudo doesn't actually work for video elements, if it did then the line I've commented on wouldn't be needed. Maybe I'll push back against the spec regarding the specific colors, but in any case ::backdrop needs to work. I was right to suspect replaced content, in StyleResolver::createPseudoElementIfNeeded it bails out because !canHaveGeneratedChildren(*parentLayoutObject), which happens for media elements, some input elements and all LayoutReplaced things. It can be "fixed" by just bypassing the check for PseudoIdBackdrop, but I doubt that's sensible. I'll create a separate review for that I think.
