PWA app is too small in the grid

I installed a PWA app (PowerPoint) in my system using the "Webpin" app (it can be found in the AppCenter). The app was added to the Applications Menu, and it looks like that:

For some reason the icon is very small, and it breaks the layout a bit. I believe that the entries' labels in the Applications Menu should be placed in the same way, no matter how big the icon is.
