Scrollbar is always getting reset to top position when chatbox is being
resized, causing current text to disappear.
Complicated solution would be to try to show as much as possible of same text -
but simple solution which should be working fine for most of the cases is just
to stay at same percentage of scroll as it was previously (with most notable
being staying at 100% - bottom of chat).
