[Henrik Skupin [:whimboo][⌚️UTC+1]]

Note that I update that tests while working on bug 1637363. So maybe I can already figure out the reason and fix it.

Comment 6

[Maja Frydrychowicz :impossibus (was :maja_zf) (needinfo me)]

The test setup seems fine to me. I wonder whether checking that navigate returns before init is important in the first place. While it does match the behaviour in Chrome CDP logs, I don't see any checks for anything like that in their unit tests.

Comment 7

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Right, I think at least for the network tests we do not have to check for the lifecycleEvent order. The only important bit here is the loaderId that this is equal. I will have that already changed in my upcoming patch for the other bug.

Comment 9

[Henrik Skupin [:whimboo][⌚️UTC+1]]

We removed the checks for the lifecycle events on bug 1637363. So this won't fail anymore.
