8e4d67498529fe734333c13a5bcd481305a0c321 webRequest reports the wrong parentFrameId for a first-level subframe
not a security fix
confidence 0.13
signal score 7.77
Source/WebKit/Shared
Classified as not security-relevant.
Triage note: Adds a parentFrameIsMainFrame field to ResourceLoadInfo and computes it in WebPageProxy so the web-extension webRequest API reports parentFrameId as the main-frame identifier correctly; a reporting-correctness parameter-threading change, not a memory-safety or security-boundary 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.
