[MlMt] Filing entire collapsed thread not working

[Jolin Warren]

A month ago, I updated MailMate from (a quite old) r5950 to r6056. Since 
then I’ve had a strange issue related to filing a message thread from 
my inbox.

I have a rule set up on my `Sent Messages` combined mailbox that moves 
any message I send to the inbox associated with the account the message 
is sent from:

![](cid:B611931A-6DD6-4975-8B92-586A3A0D5AAF at oakandapple.org

So if I receive a message ‘Test Message’ in `Inbox 1` and then reply 
to that message, after sending my reply I end up with both ‘Test 
Message’ and ‘Re: Test Message’ in `Inbox 1`. Because I have 
`Organise by Thread` enabled in the `View` menu, it appears as a single 
line, ‘Test Message’ with a closed disclosure arrow `>` to the left 
of the subject.

Normally (and before upgrading to r6056) if I use `Move to Mailbox…` 
on this collapsed thread, both the original ‘Test Message’ and the 
response ‘Re: Test Message’ would be moved to the chosen mailbox. 
This is expected, because the single line represents both messages since 
the arrow is in the closed position and the thread is collapsed. 
However, since upgrading to r6056 only the original message is moved to 
the chosen mailbox. After the move, the response email ‘Re: Test 
Message’ appears in the inbox. I then have to do another `Move to 
Mailbox…` command to move the response.

This only happens immediately after sending a message (and the rule 
being applied to move the sent message to the inbox). If after sending I 
expand the thread and immediately collapse it again (by pressing `→` 
then `←`), then a single `Move to Mailbox…` moves the entire thread, 
as expected.

I assume this is a (fairly obscure?) bug, but wondered if I’m just 
missing something? Any advice appreciated!
