Comment (by birgire):

 As far as I understand this is based on CSSLint v1.0.4 and is still an
 open request upstream:

 https://github.com/CSSLint/csslint/issues/691
 https://github.com/CSSLint/parser-lib/issues/228

 I tested the {{{fr}}} unit on http://csslint.net that uses the 1.0.3
 version and I get a parsing error.
