------- Additional Comments from Julien Chaffraix <jchaffraix at webkit.org>
I believe the patch is good enough for a review now. The flaw in the logic made
us not dirty anything (thus keeping m_hasSelfPaintingLayerDescendant set) and
the test hit an ASSERT that I fixed so we should have some coverage.
