1008507 - Moving/copying a thread destroys message order

Status: RESOLVED INCOMPLETE

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Khumba]

Attachment: Test-1.msf (source folder with correct threading)

I use Seamonkey Mail to talk to an IMAP server on localhost.  I have a thread like so in one folder (Sort by Date / Ascending / Threaded):

Test-1.msf:
- First
  - Second
    - Third

I copy or move the thread to a separate folder.  The result is:

Test-2.msf:
- Second
  - First
  - Third

Consistently, the first message ends up below the second, and the second comes up to the root of the thread.  If Third has children, then they are okay.  I've attached the .msf files for the folders above.  Repairing the folder to rebuild the .msf fixes any currently broken threads.

I experienced this bug a few years ago with Thunderbird against a different IMAP server.  I wonder if it's a race condition, because it doesn't happen when I try against my mailhost's IMAP.

NOT reproducible with installation of unofficial (by wg9s) De SeaMonkey 2.53.5 beta 1 pre Mozilla/5.0 (NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0 Build 20200727210001 (Default Classic Theme) on German WIN7 64bit:

I copied a thread by Drag And Drop to a subfolder of my IMAP account Inbox, and order inThread (as shown in SM) was ok.

But it was not a local host, but all-inkl, I can't tell whether this might matter.

Reporter is no longer active here, so INCOMPLETE for now.
