+++ This bug was initially created as a clone of Bug #1843953 +++

Steps to reproduce:

I have a lot of folders, each of which have a lot of messages (thousands). I use classic view and no message pane (separate window).  I select a folder. 


Actual results:

The new HTML-based message list randomly spins to a spot. Not the end (all messages are Read). Not FUMLUB. Just a random spot, showing messages from 2022, 2018, whatever, different each time I go back to the same folder. So I have to either pull the right-margin slider to the bottom or use the End key to get to the bottom, every time.


Expected results:

It should have gone to the spot where I had last used that folder, be it the bottom of the message list or somewhere else that I was looking at.

Reason for cloning: This bug was closed, and was basically fixed in 115.0.1 or slightly later. In the Release Notes for 115.4.1. it states,
fixed Message list did not automatically scroll to new messages when switching folders
But in fact it has regressed to the 115.0 stage. It's back.

Switching to a folder puts me back at some random spot, often near the middle of the folder, or sometimes about two screens above the bottom. This doesn't happen if I switch away from a folder and come right back immediately, but it does happen almost all the time if I come back considerably later in the day (and I leave T'bird running all the time).
