_mouseDestroy keeps mousemove and mouseup events bound

When you create a draggable object and have the draggable be destroyed while dragging, while still holding down the mouse. The mousemove events keep firing.

This is bacsause the ui.draggable.destroy method calls the _mouseDestroy()

and the _mouseDestroy() doesnt unbind the mousemove and mouseup event handlers.

To fix this add the unbind of those 2 events to the _mouseDestroy method, see below:

_mouseDestroy: function() {

this.element.unbind('.'+this.widgetName);

$(document)

.unbind('mousemove.'+this.widgetName, this._mouseMoveDelegate)

.unbind('mouseup.'+this.widgetName, this._mouseUpDelegate);

},
