There seems to be a bug when using this these 2 libraries together and trying to use CSS Pseudo-elements.
I have created a demo here: http://tappetyclick.com/fontawesomebug/. The text in the anchor which has the pseudo-element disappears and I only see the icon
If I remove the cookie consent plugin code then everything seems to work as expected see http://tappetyclick.com/fontawesomebug/test.htm
Has anyone else seen this issue or know what might be causing it.
