Issue title: Autoscroll when new message is sent
 Issue body: Is there an option to have the message feed scroll when you send a new message? Right now it doesn't show messages I sent when I mouse over and scroll down manually. Works fine for incoming messages.

 Comment 0: Same here and it happens on incoming messages as well. I've tried to get a pattern but it's kind of random. But I've noticed that I get two messages at once many times (incoming messages), and (not always) it's printed on screen my message when i write two messages one after the other. Hope this helps
