1784980 - new mail notification shows count of new from inbox, disregarding messages that came in but were moved elsewhere by filters

Status: UNCONFIRMED

(Thunderbird :: Filters, defect)

Description

[Dan Pernokis]

Attachment: TB-TEST_DisplayCountWrong.png

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:103.0) Gecko/20100101 Firefox/103.0

Steps to reproduce:

(1) Send three messages to a test account with subjects TEST 1, TEST 2, TEST 3.
(2) Use a filter to match for one of them and move it to a TEMP folder. (Use STOP EXECUTION to prevent any other fall-through filtering.)
(3) Selectively download messages for the account. (Selectively to prevent interference from other messages.)

Actual results:

All three messages were sent OK.

When polling, status line said "Downloading n of 3 messages", then finished and briefly said "Downloaded 3 messages".

Selected message (TEST 1) went to the TEMP folder as per filter.
However, popup alert displayed subjects for only TEST 2 & TEST 3 and said "Local Folders received 2 new messages".

I have always noticed that alert window may not contain all messages when they are numerous, but this is first time I've actually seen & compared the count on both sides.

Expected results:

The alert popup should have included the message in its tally (subject display and count).

Running TB 102.1.2 -- but fails same way on TB 91.12.0 also, so not a new bug in 102.
All accounts are under LOCAL FOLDERS (presumably what was intended in the popup message phrasing).

BTW, I re-tested with random sending order and it makes no difference. Also tested immediately after TB launch (which has been an issue with TB 102) and tested subsequently -- but happens regardless of when testing is performed.

Severity code 4. (And of course we need it fixed immediately :)

But seriously, this bug might also be related to Bug 1781792 where a filter that does a MOVE followed by COPY copies nothing to the output file, perhaps because after the MOVE there is nothing for COPY to link to (source from), whereas a COPY then MOVE works OK. I'm speculating that the popup alert can't see the moved message either, so doesn't include it.
