Try the Quick Insert bar in the demo and you will see that the icons are not aligned properly in the rounded bubbles.
Click the Align icon and in the submenu, you will see that there is no padding between the left, center and right align icons.
Another thing is that the selected style icon is not highlighted like it should be. So for exemple, if I select text and click the Bold icon, the icon does not turn blue like it should to show a selected state.
All these problems seem to be related to the fact that styles are applied to the <svg> nodes directly in V3. Font Awesome uses <i> nodes instead.
When using the Font Awesome Icons in V3, there are some alignment and padding problems.
Here is a JS Fiddle to reproduce the issue: https://jsfiddle.net/8cg3sdh0/
