[jochen (gone - plz use gerrit), 2015/04/13 13:07:02]

should this be in a different CL?

As long as you don't mind reviewing two CreateWindow CLs, I can certainly move
it out. This makes the ASSERTs there true.

             createWindowForRequest(request, *m_frame, policy, request.shouldSendReferrer());

         if (shouldTreatURLAsSameAsCurrent(url))
             newLoadType = FrameLoadTypeRedirectWithLockedBackForwardList;
         loadInSameDocument(url, nullptr, newLoadType, request.clientRedirect());
