I believe I have an idea as the problem here, but still no solution. Layout is rooted at the frame level, and the code in RenderSVGRoot sets the dirty layout bit on contents of its containing frame. If the containing frame has already layed out at this point, there's no infrastructure to tell the main FrameView to re-layout that frame before painting, which triggers this problem.

Now the question is how can we avoid invalidating the containing frame or triggering re-layout before flushDeferredRepaints is called.
