'scrollBy' animation behaves strangely in Chrome

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Go to http://jscrollpane.kelvinluck.com/scroll_to_animate.html
2. Enter value 5 in "scrollBy functionality" "By y:" input box
3. Click repeatedly on "Scroll by" button until the undesired effect is visible
4. If the page is zoomed to 125% the effect is more easily visible

What is the expected output? What do you see instead?
Expected behavior is to scroll down with smooth animation, but instead it 
scrolls down and then a little bit up.

What version of the jScrollPane are you using? On what browser? And operating 
system?
jScrollPane v2.0.0beta11
Chrome 19
Ubuntu 11.04

This isn't the correct place to post issues for jScrollPane. Please see:

I can see this issue but it looks like a bug in either jQuery or Chrome to 
me... If you re-post the issue to github and can provide an example where 
jQuery's animate function over a small distance on Chrome doesn't behave like 
this then I'll try to look into it further...
