"Scroll to bottom" (chat) example: Adding text too quickly breaks pane with animated scroll

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Add text to the panes by clicking the link on the page.
2. Add more text before the scroll animation for #pane1 is done.

What is the expected output? What do you see instead?

#pane1 will completely stop auto-scrolling until the page is refreshed. Even if 
you wait until the second animation is done and then click a third time, it 
won't scroll to the bottom. #pane2 will continue scrolling correctly.


What version of the jScrollPane are you using? On what browser? And operating 
system?

Not sure what version of jScrollPane is used; couldn't find it in the source 
code. This bug appears on Win7: Chrome 21.0.1180.83m, Firefox 14.0.1 and IE9.
