Three bugs caused Google's homepage to render incorrectly (elements at 0,0 or pushed off-screen): 1. <nobr> defaulted to display:block instead of inline, inflating float shrink-to-fit widths to the full viewport. 2. normalize_children ran before split_block_in_inline, wrapping inline elements in anonymous blocks before the splitter could find them. 3. Float avoidance applied to non-BFC blocks instead of BFC blocks (condition was inverted per CSS 2.1 §9.5). Also implements CSS 2.1 Appendix E paint order: floats now paint after normal flow block backgrounds via multi-phase rendering in the display list builder. Positioned elements act as mini stacking contexts and don't propagate skip_floats to their children. Net result: +10 WPT tests passing (11 promoted, 1 minor regression).
