Please run the code.
Select the first item.
Click the Remove button, which removes the first item.
Click the Show button, which says, that the selected item is "String1", although it is no longer in the list and cannot be the selected item. (The real selected item is in fact "String2")

This only works, if you removed the first item in the list.
