drop callback function runs twice in jQueryUI

Description
I have one draggable div and one droppable div. Each is nested in its own absolutely positioned parent div (see file source below). The droppable div has a callback function. The problem is that the callback is running twice. If the droppable div is not nested in the parent the callback runs correctly (once). If the parent is not absolutely positioned, the callback also runs correctly. The problem occurs in IE, Firefox and Opera (no others tested). Greedy parameter makes no difference. draggable.js, droppable.js and mouse.js were downloaded from svn on August 28, 2007.
HTML file: (Firebug console.log will output div id each time callback runs)

It seems one of the drops is coming from the element, and the other from the cursor. If you drop the draggable but the cursor is not over the droppable, only one drop is called.

I'm having exactly the same problem. I hope a fix is soon to come.
Thanks

I had the same problem. It seems that a second call is made via the mouseup event.
As a quick fix I added this code to the
dropfunction of the file
ui.droppable.js: (after line line 126, release 1.0)
if ( e.type!="dragstop" ) return; // don't handle events called via mouseup. TEMP FIX

Replying to [comment:5 rworth]:
Fixed in rev4063
The problem still occurs with JQuery UI get from http://code.jquery.com/ui/1.10.3/jquery-ui.js
When changing positionning of parent element to absolute drop event called twice.the problem does not occurs with relative positionning.
