872a0ddf5a180cb467546a9eacf7c875d3d767bb [Site Isolation] Stranded async back/forward state drops unrelated back/forward navigations
not a security fix
confidence 0.12
signal score 6.2
Source/WebCore/loader
Classified as not security-relevant.
Triage note: Replaces the AsyncBackForwardNavigationState enum (None/Pending/Cancelled) and its cancel plumbing with a single bool m_isWaitingForDelegatedBackForwardLoad governing whether a child frame blocks its parent's completion; a navigation state-machine refactor, no memory-safety or clear 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.
