           Summary: Layers need to be already updated before we call
                    adjustViewSize()
           Product: WebKit
           Version: 528+ (Nightly build)

            Status: NEW
          Severity: Normal
          Priority: P2

In FrameView::layout(), we currently call adjustViewSize() before updateLayerPositionsAfterLayout(). This is bad because adjustViewSize() can result in scrolling and painting, so layers need to have been fully updated at this point. In some cases we rely on updateLayerPositionsAfterLayout() to have been called to update RenderLayer pointers (e.g. for m_enclosingPaginationLayer) so it's really bad to not have done this by adjustViewSize time.
