enable auto scroll only when you have a chat room in focus and the app is not minimized

### Your use case

#### What would you like to do?
When I have the app open, and I'm in a chat room, that is when it should auto scroll for that room only. All other chat rooms should not auto scroll.

#### Why would you like to do it?
I don't like to have to click the button to scroll up to the last unread message

#### How would you like to achieve it?
1. app is minimized - disable auto scroll
2. app is not minimized and I have clicked on a room - enable auto scroll for that room only
3. app is not minimized and I have clicked on a room while new messages come into the other rooms - disable auto scroll for those other rooms
