Hmmm... that doesn't seem to solve the problem.

Now the new FrameView is attached to the frame, but during
FrameView::setNeedsLayout() the renderView's setNeedsLayout() is also
called.

That ends up in RenderObject::scheduleRelayout(), the pointer to the
FrameView there is different from the one we just created, so the
assertion also fails.
