LESS CSS - semicolon as parameter delimiter

According to the manual, both semicolon and comma could be used as parameter separator in mixins. I'm running LESS 1.4.1 via node.js and a file watcher. Everything is working fine, except that the IDE indicates a syntax error when I use semicolon instead of comma to separate mixin parameters. Is there a way to update/change the way PHPStorm validates LESS? As comma could be used to pass CSS lists, I would preffer to use semicolon instead.


The following code is from the LESS documentation.




The semicolon will be interpreted as an syntax error and turns underscored in read.

Any suggestions?
