LESS

.f(
	@a : {
		color : red !important;
		background : blue;
	}
);

JavaScript

const fs = require('fs');
const less = require('postcss-less');
const postcss = require('postcss')

const filePath = './test.less';
const file = fs.readFileSync(filePath);
const processor = postcss();
processor.process(file, { syntax: less, from: filePath }).then(result => {
  console.log(result.root.toString());
});

Expected Behavior

result.root.toString() should output the provided less file, completely unchanged

Actual Behavior

output is:

.f(
	@a : {
		color : red;
		background : blue;
	}
) !important;

How can we reproduce the behavior?
