Comment on attachment 217217 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=217217&action=review Oh, good catch, Brendan! > Source/WebCore/ChangeLog:8 > + No new tests because this is already covered by tests in media/media-source (which aren't enabled because the feature isn't done). Some tests are actually enabled I think. But far from the majority.
