New issue 6820 by fin...@chromium.org: Tickmark on scrollbar moves/disappears while scrolling http://code.google.com/p/chromium/issues/detail?id=6820 See also discussion <b/1049065>. I created a reduced test case for this (attached). Search for the word 'play', scroll down and notice the tickmark above the thumb which moves up as you scroll down. At the heart of the problem is a div with style "overflow: scroll;" (a nested scrollbar) and while calculating the absolute position (RenderBox::absolutePosition) for the bounding box WebKit determines that hasOverFlowClip() for one RenderObject is true, which causes the scroll offset to be subtracted from y. This causes boundingBox to appear too high up and change y pos as you scroll up and down.
