App icon in the "let's go shopping" dialog needs a shadow
The new app icons (Initiatives#2 (closed)) need a shadow adding when they are placed on a light background. Testing 3.31.1, the icon in the "let's go shopping" dialog doesn't have this, so it's not clearly defined.
Apparently the shadow can be added using the 'icon-dropshadow' class. gtk#1434 (closed) has more information.
