Comment 1

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

This fails permanently on Linux x64 18.04 fission. The last command from the test getting executed is a navigateTo.

Comment 2

[Alexandre Poirot [:ochameau]]

I see why this test is failing... but... why is it reporting a failure?
The test is flagged as fail-if = fission:
https://searchfox.org/mozilla-central/source/devtools/client/styleeditor/test/browser.ini#90-91

[browser_styleeditor_fetch-from-netmonitor.js]
fail-if = fission

Is that because fail-if accepts falsy assertion but rejects timeout?
It looks like, I don't fully follow what fail-if means!

Comment 3

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

fail-if is for the result of the file which doesn't apply because it is TEST-UNEXPECTED-PASS here.
