That's a... good question. Per spec, it should just work. I mean, the document would enter fullscreen, and dialog inside fullscreen view can be open as normal. > Does "escape" key escape out of one layer of dialog/fullscreen? multiple? all? I think, ideally "escape" key would exit fullscreen without touching any modal dialog, whatever the opening order is. It is important for security consideration, since otherwise the content may block user from exiting fullscreen. I think implementor needs to take care of that (and test should be added to verify this is guaranteed). Another security concern is that this may allow websites to fool users about what content is actually showing fullscreen. e.g. if I have <iframe src="https://www.youtube.com/something"; allowfullscreen>, when Youtube enters fullscreen, Firefox shows a message stating that youtube.com is in full screen, but with modal dialog, the parent document can actually show something different on top of the iframe. Probably this is already doable via making the iframe and its backdrop pseudo transparent, so it may not be a new concern. Not sure how important this issue is. I guess we should change the fullscreen warning to always show the origin of the top browsing context rather than the current fullscreen document. - Xidorn _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
