This bug is a regression from Safari 2.0.4 since it also affects <button>. The
regression was caused by
<http://trac.webkit.org/projects/webkit/changeset/18819>.

The RenderBox::computeAbsoluteRepaintRect() logic for the hasControlClip() case
is very strange - it doesn't look at the container o at all. I think it should
intersect with o's controlClipRect(). However, in the case of this bug, the
controlClipRect() is invalid since the container is in mid-layout (exactly the
same problem discussed in the comments for the hasOverflowClip() case).
