The drag and drop is not working probably when using with v-if

This is a js fiddle showing the problem:

As you can see from the above jsfiddle, when dragging from list 1 to list 2, "Jean" should be added, but it turns out "John" is added to the list.

I am investigating this issue. Fix will require a pretty big refactoring as previoulsy the code assumed that the displayed elements mapped 1-1 with underlying VM. I am testing a codefix, if I found no regression I may release it shortly.

I just commit the definitive code fix for the issue. I will perform more testing and if everything is OK, I will release a new version this week-end.
