Commented Issue: ComboBox doesn't close its drop down list when losing input focus to another ComboBox control [22930]

If you open the drop down list for a ComboBox and then move focus to another ComboBox control, the list from the previous control stays up instead of closing. The list DOES properly close when moving the input focus to other controls that aren't ComboBox controls.
