[WinCairo][MediaFoundation] video/audio elements doesn't work in WebKit2 It works fine in WinCairo WK1.
Created attachment 370710 [details] WIP patch Page::canStartMedia() always returns false in WK2 MiniBrowser. Do WKViewSetIsInWindow(view, true). After applying this patch, MFGetService returns 0x80004002 (E_NOINTERFACE) in MediaPlayerPrivateMediaFoundation::updateReadyState in Web process.

Before that, MediaPlayerPrivateMediaFoundation::createVideoWindow in CreateWindowEx is failing. Applying this patch, LayoutTests/media/video-resize.html can play back the video. I need to click invisible play button because the default media control doesn't show. (I guess this will be solve by enable AC.) But, WK2 can't still play YouTube while WK1 can.
