We had been pre-escaping display names like 'Math & Science' as 'Math & Science" in the REST API itself - which meant that consumers like MFEs that do their own escaping displayed the wrong thing. It's better for the API to just leave the string as-is. As far as I know, this only affects the gradebook and progress pages, both of which do their own escaping of the result from the API already.
