What kind of testing did you do you make sure we didn't regress the look-n-feel? IIRC we use more than just the icons from fabric. Maybe some typography ones are used... Would it be worth visually inspecting all places that use an ms-* CSS class?

I actually did that, inspected the icons and checked if something looked different. And no, everything I checked looked fine.

Yes, I used it on the frameworks tab, it was the only place I add it.
