FWIW, locally this fails easily with ./mach test --headless --verify comm/mail/base/test/browser/browser_threadTreeSelection.js
Tried waiting for the selection to be correct, but it never becomes correct.

Comment 14

[John Bieling (:TbSync)]

Attachment: Bug 1939704 - Ignore selectedMessageRemoved() triggered by virtual folders on cache-restore. r=darktrojan,#thunderbird-front-end-reviewers

The intermittent is caused by a behavior of virtual folders, when they
load their content from the cache and then realize that some messages no
longer exist: They "delete" them and trigger the selectedMessagesRemoved()
callback.

This patch aims to fix the intermittent and early exits the said
callback for virtual folders still being loaded.

This patch also applies the changes of D238368 to the second
switchFolder() function in the test.
