Description Ada Chan 2021-01-27 21:53:07 PST 
This is a regression from https://bugs.webkit.org/show_bug.cgi?id=220835.

In that change, m_endPromise was saved after the call to WebXRSession::shutdown(InitiatedBySystem::No), but that call could result in WebXRSession::didCompleteShutdown() if the device returns false for supportsSessionShutdownNotification() and m_endPromise would still be null then.

Not sure why xrSession_end.https.html did not time out like I've seen with xrSession_requestAnimationFrame_callback_calls.https.html.
