not a security fix
confidence 0.13
signal score 8.82
Source/WebCore/dom
Classified as not security-relevant.
Triage note: Switches hover/active detach walks and top-layer boundary checks to composed-tree inclusive ancestor helpers and adds a mousedown/mouseup press-movement threshold for base-appearance select pickers (consumePickerOpeningPress). Behavior/logic correctness for shadow DOM and native select UI; RefPtr-guarded, no memory-safety bug.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
