|1|| ||The trunk was updated to jQuery 1.8.2 in  and is still using jQuery UI 1.8.21, as in the Trac 1.0 release. I ran into a compatibility issue between jQuery UI < 1.8.22 and jQuery 1.8.x in th:#10688. The issue is described in [http://bugs.jquery.com/ticket/11921 jquery:#11921]. jQuery
|1.8.x is still using the `curCSS` variable (an alias for `$.css`), which was removed in jQuery 1.8. A workaround was implemented in jQuery UI 1.8.22, so upgrading jQuery UI on the trunk should resolve the issue.
