Bug 476291

SUMMARY
***
When I have Neochat open while many messages are being sent in the room and I read them all scrolling down to the bottom, going to another chat and then back to the first one resets the scroll position to where it was when I opened Neochat (I think) instead of remembering that I have scrolled down.
***


STEPS TO REPRODUCE
1. Open Neochat
2. Go into a quite active room
3. Read all the new messages and scroll down to the bottom
4. Go to another room
5. Go back to the first room

OBSERVED RESULT
The scroll position is back at where it was when I opened Neochat (I think, if not, it is at least a while back at a consistent position)

EXPECTED RESULT
The scroll position is where I left when I switched to the second room
