muc topic and window width
I don't know is good to start new ticket but .... ok so let's start.
If I set a long topic in groupchat I can't resize window to smaller width than topic. This occur not in all situations. If topic is longer than window width at join time I can resize to smallest available size. When I resize window to larger value than topic lenght I can't resize it back. Ohh. topic should be cut near the end of window with trailing: "(...)". Now it looks not so good.
