Comment 1

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Likely from one of your changes yesterday.

Comment 2

[Timothy Nikkel (:tnikkel)]

I'll do some investigation but unless fission is enabled (and it doesn't seem to be in any of the failures) then my changes of today have no actual affect (and even if fission is enabled their change is very small).

Comment 3

[Timothy Nikkel (:tnikkel)]

There's a lot of similar looking intermittents in this test, my first suspect is its just another way it can fail intermittently.

Comment 4

[Timothy Nikkel (:tnikkel)]

Reproduced the failure twice on this push with retriggers

https://treeherder.mozilla.org/jobs?repo=autoland&group_state=expanded&searchStr=test-linux1804-64-qr%2Fdebug-web-platform-tests-swr-e10s&revision=81d1db229eeafcf3fc89cb8739a104a006bd98d5

which is before any of my patches landed.
