not a security fix confidence 0.15 signal score 11.06 Source/WebCore/dom
Classified as not security-relevant.
Triage note: Adds Document::urlsAffectingQuirksDidChange and Page::topDocumentURLDidChange to re-run Quirks::determineRelevantQuirks on subframes when the top-document URL changes, plus an m_didApplyFacebookFlagQuirk idempotency guard and test hooks; quirks infrastructure, not a 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.
Structural signals: smartptr_member_added (+6.47), null_guard (+2.59), area:Source/WebCore/dom (+2.0)
