parse error: failed at `grid-template-columns

Hello,

I am trying to use definition in SCSS using grid-template-column like this:

grid-template-columns: [start] auto [left-edge] 276px [left-axis] 276px [middle-axis] 276px [right-axis] 276px [right-edge] auto [end];

But it fails because the labels used (no matter that those are valid) with following error:

parse error: failed at grid-template-columns: [start] auto [middle-axis] auto [end];

I suppose that this is fixed in newer SCSSPHP versions but can you have a look at it and see if you can update the plugin with the needed patch?

Thanks and best regards,
Ali Nebi
