In 6258f33fce3af55f7cdd3b5487cd04d8e53c0b38, I changed the delegate action button
behavior to select an unselected item when any of its buttons were clicked. In
retrospect, this was a mistake and causes various issues with items becoming selected
when they shouldn't be.
This patch reverts that part of the change to the prior behavior.
