No CSS classes are passed to the Font style dropdown of the CKeditor. Patch in attachment fixes this.
1 gotcha (should be changed in the help text):
in the css classes field (in the profile) you need to define the classes, the format is:
when the css classes field is left empty, no font styles are parsed
(as CKeditor expects a name and element to link to the class, some regexp voodoo will be needed)
