Martin Robinson a62f0eaf0a layout: Use box tree Fragments for offset parent queries (#36681) ... This change switches `offsetParent`, `offsetLeft`, etc queries to use the BoxTree fragments instead of walking the entire fragment tree. In addition, fragments are stored for columns and colgroups. In general, this greatly simplifies the flow of the query and prevents having to do expensive tree walks. Testing: This change is covered by newly passing WPT tests and three new failures: - /css/filter-effects/backdrop-filter-edge-clipping-2.html - /css/filter-effects/backdrop-filter-edge-mirror.html - /css/filter-effects/backdrop-filter-edge-pixels-2.html These failures are actually progressions, because now the references start to render properly whereas before they did not. Fixes: This is part of #36525 and #36665. Signed-off-by: Martin Robinson <mrobinson@igalia.com> Co-authored-by: Oriol Brufau <obrufau@igalia.com>		2025-04-25 20:25:10 +00:00
