Workaround in WebView...

[Kenneth Christiansen]

Would be nice if you could point out there places you found it to be
using the QGraphicsView wrongly. Some of the issues are due to us
having to keep supporting QWebView which can make it tricky at times,
so if you find any issue, please let us know.
