Why are these changes necessary for layout/resize?

They are not, but I think this one line change fixes hit testing for the remote
mainFrame case. Since it is related, I put it in here.

         if (mainFrame && m_frame != mainFrame) {
             FrameView* frameView = m_frame->view();
             FrameView* mainView = mainFrame->view();
