3b068d9c3d5f [intersection-observer] Some performance/power optimizations
not a security fix
confidence 0.12
signal score 7.3
Source/WebCore/dom
Classified as not security-relevant.
Triage note: IntersectionObserver::updateObservations caches Document::isFullyActive() in a WeakHashMap and iterates copyToVectorOf(m_observationTargets); adds an ASSERT(page->hasRemoteFrames()). Performance optimization plus an assertion; the copy already existed, no bug fixed.
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.
