Summary [Site Isolation] http/tests/security/cross-origin-local-storage.html is failing
Anthony Tarbinian
Reported 2026-05-14 17:01:30 PDT
When site isolation is enabled http/tests/security/cross-origin-local-storage.html fails with the following diff compared to with site isolation disabled: ``` -No value +Got value: value ``` This bug is due to the fact that the test calls internals.settings.setStorageBlockingPolicy('BlockThirdParty'); which doesn't propagate across process boundaries. This setting is defined in Source/WebCore/page/Settings.yaml and has its C++ setter generated by Source/WebCore/Scripts/GenerateSettings.rb. This setting is per-page and doesn't propagate to other processes.
