RenderLayerBacking sometimes doesn't attach scrollbars to graphics layer tree
Created attachment 148208 [details] Patch
In some cases, a scrollbar graphics layer gets created in RenderLayerBacking but it doesn't get attached to the graphics layer tree. This causes the scrollbar to disappear. See: http://code.google.com/p/chromium/issues/detail?id=129186 for a test case, or the test included in the first patch above.
I don't think it updates scrollbar geometry properly either.
(In reply to comment #3) > I don't think it updates scrollbar geometry properly either. I'm not sure I see what you're pointing out. Which code are you referring to?
Never mind, thinking of another bug that I can't currently find.
