I don't think so, I wrote a reduced testcase where the parent process opens a socketpair() and passes one end to a child process via bubblewrap, then the child process just exits. The parent process receives HUP on its end of the socket. I also modified the test to have the child just sleep, and manually sent it SIGTERM (which is how I test to manually trigger web-process-terminated). The parent process still receives the HUP event.

Yet if that were happening in WebKit, then surely web-process-terminated would be emitted. Needs further investigation.
