bug: Sortable: Two lists with floating/block elements are not working correctly.

[Santuxus]

The initial task was to have two lists displayed horizontally (one above the other) with the possibility to sort them and move the elements between both lists.

This is a working example (jQuery UI 1.8.16): ​http://jsfiddle.net/UjQVw/2/

After the update (to jQuery UI 1.9.2) ​http://jsfiddle.net/UjQVw/117/

• it's impossible to place an element in the first position
• when an element is moved in the first row, some elements in the second one start to flash / move

None of the newer versions is working either.

jsFiddle example that describes the problem was taken from ​http://stackoverflow.com/questions/9703905/jquery-sortable-connectwith-multiple-lists
