When these icons change, there should be an animation with the icon pushing upwards from the bottom of the highlight area.
This can be a bit complicated since the annotation is destroyed when the acceptance status changes and a new one is created. In order to animate from one state to the next, the annotation would have to be aware of what its prior state was and animate accordingly.
