[webkit-qt] Main frame contentsSize, iframes and frame flattening with QGraphicsWebView

[Antonio Gomes]

Hi Kalle.

I am able to reproduce the problem by running your test case. I do
believe that your expectation is right and current behavior is bug. I
will try to better understand your code tomorrow and possibly file a
bug against bugs.webkit .

I will keep you posted. Nice issue report.
