Not caching some class including colon or divider

[fredriccliver]

problem with divider character (/)

problem with colon character (:)

I'm using Tailwind CDN version. and this extension is helpful using with that.
every class recognized as a cache. but if I use some class including with (/) or (:). I cannot get a recommendation with this.
