 When adding CSS to a site via Appearance > Customize > Additional CSS, the
 syntax validator will complain if it finds markup regardless of it being
 inside a /*  */ comment.

 Steps to replicate:

  1. Go to Admin > Appearance > Customize > Additional CSS
  1. Add a comment with some markup in it
 `/* this is <a> markup test */`
  3. Hit Publish
  1. See attached error message - but note that no indicator as to what
 line contains the markup appears.

 The only workaround is to remove the markup from the comment.

 Ideally the syntax validator should not care about anything in CSS comment
