ProxyingPageAgent::frameNavigated() IPC handler builds a Protocol::Page::Frame object but sets loaderId to an empty string. The loaderId should come from ScriptExecutionContextIdentifier (document ID) which is available in the WebProcess. The PageAgentProxy should pass the ScriptExecutionContextIdentifier through the frameNavigated IPC message, and ProxyingPageAgent should convert it to a protocol string for the loaderId field. Work items: - Add ScriptExecutionContextIdentifier parameter to ProxyingPageAgent.messages.in FrameNavigated - Pass document ID from PageAgentProxy::frameNavigated - Convert to protocol loaderId string in ProxyingPageAgent - Verify frontend navigation tracking works with the new loaderId Radar cross-reference: rdar://157031522
