Can not drag/drop items in a multicolumn sortable list
===

My problem is very simple.

I have three columns that I want to be able to sort between using jQuery sortable, but for some reason the items won't start dragging. I have searched here on stackoverflow for the answer but I think I'm doing everything correctly.

- I'm setting the min height on the columns
- I've set padding/margins on the sortable items
- I've used the right options for the sortable UI command

I was able to reproduce the problem using jsbin

Can someone take a quick look and tell me what I did wrong?
