JQuery and animate backgroundPosition no longer works in version 1.5.0 from Google CDN

I recently upgraded from loading JQuery 1.4.4 to 1.5.0 with Google CDN. When I upgraded, my backgroundPosition animations stopped functioning.

For example, I used to have:

$(this).stop().animate({backgroundPosition: ['-1800px 0px', 'easeOutExpo']},5000);

This no longer works in v开发者_StackOverflow中文版ersion 1.5.0 loaded from Google CDN. Let it be noted that I am using JQuery UI 1.8.9, also loaded from Google CDN.

Has anyone else encountered similar problems?

This is actually a known bug, it's breaking quite a few things with jQuery UI. My recommendation, for the interim is just refer to an older jQuery version, something like this:

http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js

1.4.4 is the last version that works with background-position, i know i spent days trying to debug my code, without knowing that fact.

I've tested it working up to 1.8.3. It looks like Keith Wood the creator updated it June 2013. You should really check out his page. Here
