          ASSERTION FAILED: !needsLayout() seen again

        * page/FrameView.cpp:
        (WebCore::FrameView::layout): Removed the midLayout guards around
        the calls to invalidateSelection() and updateWidgetPositions(). Those
        calls may dirty the layout, but in that case they also update it, so
        they should be allowed to do it. Added an ASSERT to make sure that when
        they return, the root is not marked for layout.
