ProxyingNetworkAgent::requestWillBeSent currently creates a hardcoded Initiator with Type::Other. To support proper initiator information (script stack traces, parser URLs), ScriptCallStack/ScriptCallFrame need IPC serialization. Work items: - Add IPC serialization for ScriptCallStack / ScriptCallFrame - Update ProxyingNetworkAgent.messages.in RequestWillBeSent to include optional Initiator - Build Initiator in NetworkAgentProxy::willSendRequest - Forward through IPC and reconstruct in ProxyingNetworkAgent Radar cross-reference: rdar://143782685
