Open any flash page e.g. Youtube with QtTest on Mac and click "setttings" on Flash context menu, you cannot click any thing on flash setting dialog. However the issue doesn't happen to Mac native WebKit, I cannot click flash setting dialog with miniBrowser on Mac. The issue exists on both 64-bit and 32-bit QtWebKit whether Qt4 or Qt5. It' a blocking issue for any program using camera with QtWebkit and flash player e.g. http://testmycam.com/ beacuse there is no way to click "Allow" on flash Camera and Microphone Access dialog. The issue exists before Bug 72358 and still exists after Bug 72358 patch. Please notice that you use tab to switch focus between buttons on flash setting dialig, but you cannot click "Enter" to click focused button.
It's very simple to repdouce. Just open http://testmycam.com/ in qttestbrowser on Mac, you cannot click "Allow" button.
