title: drag and connectToSortable into sortable DIV inside the iframe
body: <p>I was trying to drag a element from main page to a iframe inside it with sortable div inside frame</p>
  
  <p>i was able to make div sortable and connect draggable to sortable inside it but the position the element is dropped is computed wrong and sorted at wrong place </p>
  
  <p>may be because the mouse coordinates inside iframe have different position with main page </p>
