gulp-csslint is not picking up my .csslintrc

[Nightfirecat]

Test case:

$ ls -A
.csslintrc  gulpfile.js  node_modules  package.json  test.css  yarn.lock

$ cat package.json
{
  "name": "test",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "devDependencies": {
    "gulp": "^4.0.0",
    "gulp-csslint": "^1.0.1"
  }
}

$ cat test.css
.foo.bar {
  width: 300px
}

.foo > h1 {
  color: grey
}

.bar > h1 {
  color: blue
}

.foo {
  border: 2px solid black;
  width: 20px
}

$ cat gulpfile.js
const gulp    = require('gulp'),
      csslint = require('gulp-csslint');

gulp.task('css', function() {
        return gulp.src('test.css')
                .pipe(csslint('.csslintrc'))
                .pipe(csslint.formatter());
});

Expected output: (using csslint CLI tool)

$ csslint test.css


csslint: There are 2 problems in D:\Documents\git\test\test.css.

test.css
1: warning at line 5, col 8
Heading (h1) should not be qualified.
.foo > h1 {

test.css
2: warning at line 9, col 8
Heading (h1) should not be qualified.

Actual output (using gulp task)
