1. Opening chat with user1

2. A chat window with title *"Chat with User1" shows

3. Sending "hi" to user1

4. Closing chat with user1 (selecting "Close chat") from settings

5. Opening a new chat with user2

6. A chat window with title *"Chat with User1" shows

7. The new chat window also shows the "hi" I sent to user1

8. "Show chats" option shows only chat with user2

Now the question: who am I talking to?
