8411b9a979791c55b2407d632f3f20bec7f2aa18 [Site Isolation] Make noopener windows eligible for the bfcache
not a security fix
confidence 0.12
signal score 7.67
Source/WebKit/UIProcess
Classified as not security-relevant.
Triage note: Introduces preferredProcessFromOpener and canShareProcessWithOpener() (checks shared-process, dataStore, lockdown/enhancedSecurity, shared preferences) and replaces hasPageOpenedByMainFrame() with shouldReuseMainFrameOnProcessSwap(). Process-swap/isolation policy plumbing for a feature; checks are present rather than a fixed 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.
