[Users] Exit of the message window with the up key

[David BERCOT]

Hello,

I use Claws-mail version 3.9.3-184-g39672a on Debian.

Since a couple of updates, I have a new comportement inside the message
window.
Before it, pressing the up key did not leave the message window (it
stopped at the top of this window).
Now, if I'm at the top of the message window, pressing the up key send
the cursor to the subject field and so on...

I've search in the preferences but I did not find anything about this.

Do you have any solution ?

Thank you.

David.
