Something is creating a hidden window in an xpcshell test [log error line](https://treeherder.mozilla.org/logviewer?job_id=334078690&repo=try&lineNumber=7159):
> [task 2021-03-22T23:31:20.770Z] 23:31:20     INFO -  PID 12532 | [Parent 12532: Main Thread]: D/DocLoader DocLoader:2031f1bf000: OnStartRequest[2031f50be40](documentchannel:resource://gre-resources/hiddenWindow.html) mIsLoadingDocument=false, 1 active URLs

I'll modify [CreateHiddenWindow](https://searchfox.org/mozilla-central/rev/36f79bed679ad7ec46f7cd05868a8f6dc823e1be/xpfe/appshell/nsAppShellService.cpp#95) to crash under xpcshell and hopefully that points at a useful call stack.
