The list of messages filtered by the sender. Displays the top of the message. 1. Scroll through the long message to the bottom; 2. Delete the message; 3. The message is updated to the next, but the bottom of the message is displayed. Instead of the top of the new message, we see its bottom.
I had a similar problem: deleting messages was OK, but when I opened a folder with an unread message, which is then automatically loaded, the message view wouldn't scroll up. I fixed it by scrolling the view before the new message is loaded - see the attached patch.
