Unreliable underlining of collapsed thread subject to indicate unread children.
|Reported by:||kaz||Owned by:|
I discovered this during the development of the patch that I attached to #1486701. (I didn't introduce this because I can reproduce the behavior in the unpatched code).
Basically, the feature is not 100% reliable. Sometimes you can mark a message unread, collapse the thread, and the collapsed thread row has no indication that there is an unread message: the underlining is not there.
The problem is specific to particular threads. It may work fine in other threads in the same folder, but not others.
Selecting a different folder then coming back to that folder does not resolve the problem; the same threads still exhibit the issue.
Doing a browser refresh makes the problem go away; after a refresh, the thread roots show correctly. Of course the problem can come back.
Reproducing the problem requires a little bit of exercise.. You need an IMAP account with some folders and threads, and just move around between folders expanding threads, marking messages unread, collapsing. You will see it sooner or later.
Sorry to be reporting against 0.4-beta when 0.4-stable is out; too lazy to update.
