Sortable "out" event is being fired on drop

This may not be a bug, but it's leading to buggy behavior that did not exist in 1.5

When you drop a sortable, the "out" event is fired.

The issue I am running into is that the ui.helper property is set to null, and any attempt to modify the helper is causing the script to break.

To see this in action just do this in tests/visual/sortable/sortable.html

$("#sortable").sortable({

helper: function() {

var instance = this;

return jQuery('<div style="width: 50px; height: 50px; background: #000"></div>')[0];

},

out: function(event, ui) {

var instance = this;

console.log('fires when leaving the sortable, and when the sortable is dropped', ui, ui.helper);

},

});

It would be possible to check in the out callback, but I'm not sure this call back should logically be called (because the helper never actually left the sortable, hence, it's not really out, AND it's different from behavior in 1.5).
