[Interest] Transparent WebEngineView hides the elements behind it

[sevenrats at tutanota.com]

 Ifwe make a Qt WebEngineView transparent it will not allow viewinganything behind it. This includes other Qt Quick elements or stuffdrawn behind it using OpenGL. Instead it causes whatever the previousframe was to be repeated. So for instance if we display an image inthe WebView and get rid of it, the image will still be there as a"ghost".


Arewe doing something wrong with the new rendering api or is this a bug?
