      updateScrollInfoAfterLayout() calling setHasHorizontalScrollbar() caused updateScrollbarParts()
      to call setChildNeedsLayout() on the overflow, because the RenderScrollbar was created with
      the default thickness instead of the thickness specified in style. This led to the the overflow’s
      parent to be re-marked for layout during its own parent’s finishDelayUpdateScrollInfo(), and
      the result was that at the end of RenderView::layout(), there was a dirty renderer.
      
      * rendering/RenderScrollbar.cpp:
      (WebCore::RenderScrollbar::RenderScrollbar): Set the frame size in the 'display: none' and
      'visibility: hidden' cases as well.
