Classified as not security-relevant.
Triage note: PlatformCALayerRemote::moveToContext reorders layerDidEnterContext before layerWillLeaveContext and, under HAVE(AVKIT), carries the layer's HTMLVideoElement into the new RemoteLayerTreeContext via videoElementForLayer/videoElementForContext. A fullscreen-video remote-layer-hosting correctness fix; no memory-safety or attacker-reachable logic bug evident.
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.
