This didn't happen in version 91?

Not sure, but I don't think so. Now I'm running 102 and not going to switch back. However I don't like that behavior. Imagine this in Firefox...

To clarify the STR: It isn't necessary to scroll to the bottom to see the issue. Visiting the tab shows the top no matter where the scroll bar was left in the previous viewing of the message.

Reporter, do you still see this issue when using the latest version?
What information can you add to clarify the steps to reproduce this issue?

I just reproduced this with 102.9.0 on Ubuntu.

Steps to reproduce:

1. Open a long message in a new tab.
2. Scroll down in the message.
3. Return to the primary tab.
4. Return to the message tab.

Expected:
4) The scroll position in the message tab is the same as was left in step 2.

Actual:
4) The message is scrolled to the top of the tab.

Can this be reproduced with beta?

Comment 8

I cannot reproduce the issue with 114.0b1.

But using messages in tabs with 114.0b1 is frustrating in a different way. See bug 1833134.
