Since I guess that the creator intended to have a special formating of the corresponding text passages, but forgot to add the defintions to the css, it would be good to be informed about the missing defintions to be able to format these passages.

I suppose cssRemoveUnusedSelectors plugin could be modified so undefined classes would be added to the stylesheet as a blank selector ( .whatever {} ) but not sure how much easier that would make the job. Are you volunteering to code and test this?
