Opening a message using keyboard shortcut does not mark it as read.
Steps to reproduce:
- Have one unread message. You can just toggle the top one to be unread.
- Press I for Inbox -> 1 to go to the first message (or 2, 3, etc for other messages).
Expected: Opening a message marks it as read. Actual: It does not. However, left-clicking with the mouse does mark the message as read when opening it.
