Font Awesome needs a style class as well as a name: fa-chart-column alone matches the
base .fa-chart-column rule, which sets a glyph but no font family, so nothing renders.
A value that already names a style is returned untouched, including the older one-class
fa fa-folder form that the generated forms still use.
An icon value the browser can actually draw.
