The Acid1 test has a bit of an unusual background - the html and body tags have different background colors. Our painting order of the DOM was such that the body background was painted first, then all other elements were painted in-phase according to Appendix E of CSS 2.1. So the html element's background color was painted over the body background. This removes the special handling of the body background from InitialContainingBlockBox and now all boxes are painted in-phase. Doing this also exposed that we weren't handling Section 2.11.2 of the spec; when the html background is unset, the body's background should be propagated to the html element.
