### Describe the bug

### Expected behaviour
The icons should be collapsed

How do you think the program should work? Add screenshots and code blocks if necessary
I think there should be an option on Preferences like "Collapse when the focus is changed". Also Bartender 4 works that way, if I click anywhere other than the bar, it collapses like, also like on the Windows tray section

### Environment
