1. Open the drop-down menu.
2. Use up and down arrows to highlight an item.
3. Close the drop-down menu by clicking outside it or pressing Esc.
4. Open the drop-down menu again - you will find that the item you highlighted in step 2 is still highlighted, while the actually selected item is not.
5. Press arrow down - you will see two highlighted items, neither of which is actually selected.
