Summary [Site Isolation] testRunner.globalFlag doesn't work with Site Isolation

Reported 2026-01-09 16:13:08 PST
Several tests in LayoutTests/http/tests/security rely on testRunner.globalFlag to communicate between different frames. Previously, with site isolation enabled, this flag would not be shared across different processes. This caused several LayoutTests to timeout since they use testRunner.globalFlag to indicate when an event has ocurred. Since testRunner.globalFlag wasn't updating across processes they were stuck waiting forever.
