b8e586fe8c3068f916f90de3e2ccd5e305af81fe [Site Isolation] New pages added to BrowsingContextGroup are not registered with shared process
not a security fix
confidence 0.18
signal score 6.07
Source/WebKit/UIProcess
Classified as not security-relevant.
Triage note: BrowsingContextGroup::addFrameProcessAndInjectPageContextIf and addPage refactor when a RemotePageProxy is created, skipping pages whose main frame is already hosted directly by the process and picking a representative site in shared-process mode. Process-model refactor; no identified attacker-reachable 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.
