568cf14ae6de86a8bc578420940f6b06f0bb648d AX: In isolated tree mode, a fieldset does not expose its legend as its title UI element
not a security fix
confidence 0.1
signal score 7.77
Source/WebCore/accessibility
Classified as not security-relevant.
Triage note: Reworks how a fieldset's legend labels it and skips ARIA-hidden labels unless referenced; accessibility correctness refactor (isFieldset via elementName, markRelationsDirty) with no memory-safety/security 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.
