XF 2.2 Dropdown BB code button will not render some FA icons in editor.

[philmckrackon]

I am trying to add a drop down BB code button to the rich text editor with a fa icon. It will render the icon in the editor when it is a short name such as fa-briefcase but not a long named icon such as fab fa-wikipedia-w. The icon does show in the admin panel though and works for individual buttons.
Not sure if this is a bug. XF 2.2.16 pl2
Thoughts?

Short name showing (fa-briefcase):







Long name showing (fab fa-wikipedia-w):

I don't think we expected a custom icon style (ie. regular/solid/light) to be set for dropdown icons, but it inadvertently means brand icons can't be used there. You can submit it as a bug.
