A failing tree dump would be super helpful regardless of debugging.

That said, my theory is that we don't allocate the layer as we should. To confirm that, you could break into RenderBox::scrollLeft - as this is called from the test page - and check that hasOverflowClipWithLayer() is true. If it isn't, I would dive into RenderBlock::addOverflowFromChildren and see why RenderBox::addLayoutOverflow doesn't allocate the layer.
