94f9b7905e3ce9a3d7497f26b563adcad6b7525f Speed up FrameTree::containsRemoteFrame and related methods
not a security fix
confidence 0.15
signal score 12.92
Source/WebCore/dom
Classified as not security-relevant.
Triage note: Replaces Page::m_remoteFrameCount/hasRemoteFrames() with a per-FrameTree m_remoteFrameDescendantCount maintained in appendChild/removeChild/replaceChild/detachFromParent, with containsRemoteFrame() reading the count; heavy on ASSERTs and remoteFrameDescendantCountSlow() verification. Site-isolation bookkeeping refactor, no identified 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.
