:Gijs, since you are the author of the regressor, bug 1810995, could you take a look?

I don't really think the regression is all that real - we just got unlucky. We hit:

21:55:50 INFO - TEST-UNEXPECTED-FAIL | <snip> This test exceeded the timeout threshold. <snip>

This is when running in chaos mode on opt. The previous messages have:

21:55:50 INFO - Buffered messages logged at 21:55:47
21:55:50 INFO - Leaving test bound process_switching_through_navigation_features

That is the last subtest in that file. So the test had in fact finished but we hadn't run cleanup etc.

[task 2023-01-19T21:55:50.154Z] 21:55:50 INFO - TEST-OK | browser/base/content/test/tabs/browser_privilegedmozilla_process_pref.js | took 61563ms

suggests the cut-off is 60s and we just ended up slightly above that.

The change in bug 1810995 renamed a method that the test calls and updated the test to call that renamed method, it wouldn't otherwise cause anything to slow down.
