The problem seems to be that to RenderLayer::computeScrollDimensions uses
clientHeight/clientWidth from the parent DIV to determine the amount of
available space for the child DIV. ClientHeight/Width does not include the
scrollbar sizes and thus it is wrongly determined that the child DIV will not
fit inside the parent without scrollbars. I'm not sure if this should be fixed
in computeScrollDimensions like done in the patch or if the scrollbars should
be removed before calling computeScrollDimensions (called through
RenderLayer::updateScrollInfoAfterLayout)
