> Reordering / Drag & Drop: demos appears to fail in IE7 after a first item has been reordered: selecting items and moving them up or down in the list is accomplished when clicking on the arrows, but submitting reorder re-arranges the items in a different order in the list, and also the previously selected items appear as selected. (not an issue in IE9, FF21, Chrome27).

Steps:
- open ace:List -> Reordering demo in IE7
- select one item from the list, and click the down arrow to move it down one position -> item is moved down the list.
- press Submit Reorder button -> the order of the items from the right side updates accordingly.
- repeat the previous two steps with the same item, or select another item from list and reorder; after one or two other trials, the selected item will jump to a different location when submitting reorder; if using the same item being moved repeatedly, after two or more reorderings the item will be duplicated in the list as in attached screen shot.
