Per CSS 2.1 §9.2.1, anonymous block generation should only consider in-flow elements. Floats, absolutely positioned, and fixed positioned elements are out-of-flow and should not trigger anonymous block wrapping. Previously, normalize_children() classified floats as "inline-level" (because is_block_level_child returned false for them), causing them to be wrapped inside anonymous blocks. This gave floats the wrong containing block and broke clear interaction with siblings (e.g., ACID2 .nose/.smile). Add is_out_of_flow predicate, exclude OOF elements from the has_inline check, and add a dedicated branch in the wrapping loop that flushes pending inline runs and places OOF elements as direct children. Net WPT improvement: +6 passing tests (9 promoted, 3 regressed). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
