dragsort won't initialize if all lists are empty

[mcm-ham]

I have 3 lists, initially empty, filled dynamically later.
If I call $(list).dragsort({ dragSelector: '.item' }) when they are empty, nothing happens.
However, if at least one of the is nonempty, all of them get initialized.

This is clearly a bug, either it should initialize either way (preferred) or only for nonempty lists.
Happens in current firefox & chrome, not tested elsewhere.

For the, the workaround of creating the lists with a placeholder item, initializing and then deleting the item works.

Additional info:

I can actually make it intialize almost fine using$('.orderselect').dragsort({ itemSelector: '.option', dragSelector: '.option', placeHolderTemplate: '' })

But then, dropping doesn't work - the item returns where it was.

If I add$('.orderselect').dragsort({ itemSelector: '.option', dragSelector: '.option', placeHolderTemplate: '' })it works, but weird - an empty option appears while dragging, which I don't want.
