Comment 5

[Sam Foster [:sfoster] (he/him)]

A found a few cases where the hint popup might be lingering between tests so overlapping popuphidden events might get us into a confusing state where we attempt to verify a confirmation hint when the browser should be attached to (its anchorNode) has gone away. We also don't need to wait for the hint to self-close each time, so this test should run a bit faster now.

But that's still not fixing the underlying problem apparently: https://treeherder.mozilla.org/#/jobs?repo=try&revision=aee3bd7a56b4f642691361c2f6586cd8bba8c8f8&selectedJob=292768331

So I'm still investigating.
