Comment on attachment 399426 [details] Patch Do we have any way to add tests for quirk? It would be better to add a test if at all possible.

Comment on attachment 399426 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=399426&action=review > Source/WebCore/html/MediaElementSession.cpp:319 > + if (topDocument.hasHadUserInteraction() && document.quirks().shouldAutoplayForArbitraryUserGesture()) We should probably update MediaElementSession::updateMediaUsageIfChanged as well, since it is doing document.hasHadUserInteraction() && document.quirks().shouldAutoplayForArbitraryUserGesture() as well. Maybe we should add a test for that document/topDocument change where the iframe did not interact but the top document (or another iframe) did. That would require Internals to be able to set the document quirks shouldAutoplayForArbitraryUserGesture() value.

We don't have the support to test quirks for now. We may need a non-trivial patch to enable it. Filed a bug for it: <webkit.org/b/212047>.
