[Bug] Missing active mailbox indication in the compact navigation bar. #752
Description
Describe the bug
In compact form, it is not possible to tell which mailbox is currently active in the left navigation bar. In expanded form, there is a vertical blue line next to the active mailbox. In compact form, it is not. At the same time, the icons of the individual mailboxes take up an unnecessarily large amount of vertical space.
Expected behavior
The same active mailbox designation as in the expanded form of the navigation bar.
