This isn't in the modernizer CSS. I combined the old base import from https://github.com/wet-boew/wet-boew/pull/5312/files#diff-ba500a18318aaaf0666a6575b6ad2464L62 with the base in the polyfills, and it is still loaded in the core https://github.com/wet-boew/wet-boew/pull/5312/files#diff-ba500a18318aaaf0666a6575b6ad2464R90
