Describe the bug

Some of our icons appear to be a little over-optimized. Their edges are simplified too much, resulting in imbalanced shapes and clipped edges.

I found and cleaned this up in an instance of the Facebook icon (#9178), but I'm realizing now this effects other icons too (see examples below).

I can see this occurring on the File, Table, Button, Archives, Latest Comments, SoundCloud, MixCloud, ReverbNation, and Spreaker block icons as well.
