Steps to reproduce:

In the "Mail Thread View" that displays the list of current mail items in a mailbox, the Collapsed State of threads is only persisted between changing mailboxes when a mail item in a thread is selected.

Open a mailbox, then expand several different email threads in that mailbox's mail items view. Select a mail item in one of the threads.
Select another mailbox.
Go back to the original mailbox.

Actual results:

The original mailboxes mails threads are all collapsed EXCEPT for the thread containing the selected mail item.

Expected results:

By default, all mail thread's expand/collapse state should persist between display, including after Thunderbird is closed/restarted and when switching between mailboxes, regardless of which thread's email item is selected. A mailbox and its contents/threads should be drawn in the same state in which it was left when it was last closed.

Perhaps this should be made into a settings option called: "Persist Thread Expansion State in Mail Lists".

A very similar bug is bug 1866250. To my knowledge, individual thread states were never persisted.
