 There seems to be an issue with jQuery UI (sortable) 1.9.1 and above that
 affects (rather severely) sorting of elements inside sortable source and
 target containers. I haven't seen this affect core, but since WP has been
 shipping with one of the affected versions (1.9.2) since 3.5, I'm worried
 about potential repercussions on WP theemes, plugins or projects relying
 on this script. For instance, Ultimate Tinymce, by Josh Lobe and myself
 (recently), has been affected by this.[[BR]]
 [http://elblawg.com/jqueryui-test/ Here] is a testing platform I created
 on my server about the problem. Choosing any version of UI newer than
 1.9.0 will result in said behavior.[[BR]]
 [http://bugs.jqueryui.com/ticket/9041 Here] is the ticket I submitted to
 jquery UI Trac and [https://github.com/MarventusWP/jquery-
 ui/commits/master here] the Commits to their github project.[[BR]]
 Finally, as recommended by Andrew Nacin on the wp-forums list,
 [http://jsfiddle.net/Marventus/THwqS/1/ here] is a JSFiddle that
 reproduces the problem.[[BR]]
 I am not really sure what to do about this, but I thought I should leave
 it on record just in case.
 Thanks!
