Summary Web Inspector: Site Isolation: Page domain bootstrap script injection
Blaze Burg
Reported 2026-02-28 11:55:30 PST
Page.setBootstrapScript must forward the script to all WebProcesses for injection via didClearWindowObjectInWorld. New OOPIF WebProcesses must also receive the script. Work items: - ProxyingPageAgent stores script and forwards to all WebProcesses via IPC - PageAgentProxy::didClearWindowObjectInWorld evaluates stored bootstrap script - New WebProcesses receive bootstrap script on creation - Handle timing: script must be pre-cached in WebProcess to avoid IPC latency race Radar cross-reference: rdar://157031522
