dcb25ff14a12a2975d67b3de8d90bd9d42162407 Second CSS Highlight sharing a Range with an already-registered Highlight never paints
not a security fix
confidence 0.15
signal score 6.3
Source/WebCore/dom
Classified as not security-relevant.
Triage note: Adds HighlightRange::m_needsPositionUpdate (and setAllRangesNeedPositionUpdate/didUpdatePositions) so setFromMapLike marks ranges for position update and collectHighlightRangesFromRegister/updateHighlightPositions honor it. This is a highlight-rendering correctness fix with no identified memory-safety primitive.
