Clicking on a thread should focus the thread composer

[ara4n]

Steps to reproduce

1. View a room with RightPanel hidden
2. See someone's started a thread
3. Click on the thread to view it
4. Type a response
5. Feel upset that the response went to the main timeline rather than the thread that you just clicked on to view.

Outcome

What did you expect?

I expected the act of clicking 'into' a thread to transfer composer focus to the newly visible threadpanel

What happened instead?

Instead, composer focus remained on the main timeline
