On the list of the gained items (when game on pause, or after game finished), when clicking on an item, a description appear, and when clicking outside, the description disappear. To be exact, the description become slightly bigger, and become smaller and smaller until disappearing. If you click outside the description when the description is slightly bigger, the description will restart the disappearing animation, and become even more big, and if we click a lot of times very quickly, the description will restart its animation again and again, and become bigger and bigger.
