+Summary: ListBox: Setting SelectedItem to null doesn't match MS behaviour
+
+Setting ListBox.SelectedItem to null should unselect currently selected
+items and also should set SelectedIndex to -1.
+
+Steps to reproduce the problem:
+1. Compile the sample.
+2. Select any of the items in the list box and then press the "Set
+SelectedItem" button.
+
+Pressing the button should unselect the currently selected item (additional
+info is printed to the console, about both SelectedItem and SelectedIndex;
+those ones should have values of "null" and -1, respectively).
