Comment 26

[Hsin-Yi Tsai (she/her) [:hsinyi]]

The test case has been disabled.

Comment 27

[Andrew McCreight [:mccr8]]

This still happens frequently when running the test locally. I think the timeout happens right here the first time the test attempts to navigate to about:blank.

Calling startLoadingURIString before browserLoaded looked a little sketchy to me, so I tried reversing the order (and adding a URL to the latter because why not) like this but it didn't help:

let loaded = BrowserTestUtils.browserLoaded(browser, false, "about:blank");
BrowserTestUtils.startLoadingURIString(browser, "about:blank");
await loaded;

Maybe navigating to something besides about:blank would be less problematic? Maybe there's some kind of Fission process switch angle going on here and navigating to a same-site page would avoid problems.
