 When loading up the customizer (independent of which theme is used),
 FireFox complains about the dashicon font being used as it is rejected by
 their sanitizer.

 The exact error output from FireFox

 {{{
 downloadable font: rejected by sanitizer (font-family: "dashicons"
 style:normal weight:normal stretch:normal src index:0) source:
 http://192.168.1.4/wp_vanilla/wp-includes/fonts/dashicons.eot
 }}}

 My test site is at `http://192.168.1.4/wp_vanilla/` in the above example.

 It is being triggered at `dashicons.css:1:12`, this only occurs in the
 customizer, anywhere else using dashicons in the admin appears fine.
