Unfortunately, Wikia does not make official announcements for most of their changes. However, this is certainly the result of something changing on their end. Apparently, someone decided to disallow the use of in-line CSS variables. Why? I don't know. However, the most common reasons for the changes Wikia makes are (in no particular order):
 * security
 * portability
 * lower server load
 * plays better with other backend code
