The only way to make the list re-sort is to sort by a different field and then sort by label again. (The same holds for using the View->sort by menu) Reproducible: Always Steps to Reproduce: 1. Sort mail messages by label. 2. Change the label of a mail message. 3. Choose sort by label again, without sorting by something else first. Actual Results: The order of the messages changed from ascending to descending, but the changed message stayed in the same relative position. Expected Results: The order should have changed, but the list should have been re-sorted as well.
