This seems to make it pretty solid.

Sent to try now https://treeherder.mozilla.org/#/jobs?repo=try-comm-central&revision=70b65383df399e43e9df6f2c0e7ae311eccc0eec

For the assert_selected_and_displayed, I don't know how that ever works without passing the controller. Looks like it did the wrong checks and passed accidentally.

The controller is assumed to be mc if not passed, but that's not obvious it's so better to be explicit.

[Geoff Lankow (:darktrojan)]

The test failed on Mac and Windows on your Try run. I'm not sure if this is related to the other noise or not, so probably best to try Try again.

Comment 7

Attachment: Bug 1663209 - currentIndex should return -1 when tree.view.selection is null. r=ntim

Likely happens mostly in automation. At least Thunderbird have places where the view is going to be replaced and the selection is cleared first.
