This leak seems to be occurring quite frequently, just got 2 on one try run.
It leaks while running tests from: devtools/server/tests/browser/

Sometimes, the types of objects being leaked helps:

But here, we are leaking pretty generic objects.
BackstagePass is the global object for JSMs or JS XPCOM.
For the record this failure only seems to happen on artifact builds, which is why it is not often spotted by sheriffs. But it s quite frequent for artifact builds on try.

:jdescottes, do you think this is a debugger bug?
It's actually unlikely, it's triggered by one of the tests in https://searchfox.org/mozilla-central/source/devtools/server/tests/browser/browser.ini

My attempts at narrowing it down to a single test were not fruitful, could only get the failure regularly when running most of the folder ...
