math loading errors with libsass 0.22.0

Disclaimer: Just in case, I am not a Python / SASS pro in any means...

It looks like this lib breaks when used from https://github.com/orzih/mkdocs-extra-sass-plugin and when loading the recent v3.0.0 version of https://github.com/at-import/breakpoint/ . Looks like it is similar to twbs/bootstrap-sass#1230

Nevermind https://discourse.gohugo.io/t/cant-use-sass-math-div/33087 , libsass is not supported at all. So the root cause was at-import/breakpoint@8f400aa in breakpoint 3.0 that reintroduced sass:math dependency
