In Thunderbird only one of newly archived and marked as read before is marked as read in All Mail directory.

Reproducible: Always

Steps to Reproduce:
1. Wait for a few messages to arrive in Inbox, thus being marked as unread.
2. Mark all of them as read, then archive them.
3. Click on All Mail folder.
Actual Results:
Only one of recently archived messages is marked as read (usually the newest one), the rest must be marked as read again.

Expected Results:
All of recently marked as read in Inbox and archived mails should be marked as read in All Mail folder, too.
