Details
As I mentioned here, when looking at some recent mochitest browser chrome test failures, I noticed that some are leaking windows created during a test. This is supposed to be caught by the checking in /testing/mochitest/leaks.py that uses the ++DOMWINDOW and --DOMWINDOW logging. If I search for intermittent-failure bugs in Bugzilla where the summary contains "until shutdown", I don't see any with activity since July of 2023, so it is possible that this testing has been broken since then. I haven't had a chance to investigate what might be going wrong yet. It is possible that the leak detector isn't actually supposed to report windows that are never collected before shutdown, but concerns me that we have zero active intermittent bugs on file for this kind of failure.

Aryx reminded me that most failures are now grouped by test. They pointed me at a query which shows that we are seeing these failures still. Phew! I forgot about that because I was looking at leakcheck and LeakSanitizer failures which aren't.
