We accidentally regressed back in 9.5 and dropped support for inline CSS comments. PostCSS always parses these as pass-through (and not a syntax error), which can cause problems when minifying.
Browsers do a similar thing and ignore the comments.
To ensure we generate valid CSS, this adds support for stripping the CSS comments from the build.
