jQuery 1.4.3 animation method behaves strangely when animated to left: over 10'000 px

[mail@…]

Steps to reproduce:

1. Create one huge container (mine is 12200 pixels wide)
2. Fill it with images (to be more easy to observe the animation)
3. Set it's position to relative
4. Try to animate it to -10300 pixels

Expected behavior: animation is smooth and continuos

Observed: Container shakes strangely until reaching the desired left position.

Environment: All browsers (FF 3.6, IE 7+, Chrome)

jQuery versions: 1.4.3 and 1.4.4 . 1.4.2 works fine

I found this bug when creating a carousel with jcarousel plugin with 20 items, each one 606 pixels wide.

This sounds very much like an issue with the actual code implementation rather than a problem caused by jQuery core.Could you please submit a valid test case on jsFiddle.net that reproduces your issue so we can investigate further?.

Alright, I took the time to put together a valid fiddle and things appear to work just fine. ​http://jsfiddle.net/boushley/dgqsw/1/

As boushley correctly points out this appears to be working fine. If you are doing something beyond what it in the above test case on jsFiddle and would like to re-open this ticket, please let us know.

Hi, I changed a bit the code in jsfiddle so now the bug reproduces properly. The left position now changes 606 pixels on click. So you have to click a couple of times. And animation easing changed to 'swing'.
