Steps:
1. Click `Create new chat`
2. Create pending thread (don't select any users or select set of users, which doesn't match to any existing thread)
3. Close composer by click `X` button
Now, app is currently focused on the first thread from the thread list.
In other cases, when we send a message to a new thread or we close `ChatThreadComposer` on an already existing thread, app keeps focus on the current thread.
