Note that bug 1530253 just made the test accidentally pass sometimes. Our implementation is still broken.

[Cristian Tuns]

Hi, can you please take a looks at this? https://treeherder.mozilla.org/logviewer?job_id=385980413&repo=autoland still happening on autoland but with TEST-UNEXPECTED-FAIL instead of TEST-UNEXPECTED-PASS

Comment 13

[Hiroyuki Ikezoe (:hiro)]

Cristian, mind filing a new bug for the unexpected failure? I'd think it's a real race condition of which I wasn't aware.

Comment 14

[Cristian Tuns]

Hi, sure. https://bugzilla.mozilla.org/show_bug.cgi?id=1782461
