Hello, we’re implementing SonarQube for our project and are facing a few issues, in particular, we’re heavily using the “SCSS to JS” export pattern as described here: [https://www.bluematador.com/blog/how-to-share-variables-between-js-and-sass](https://www.bluematador.com/blog/how-to-share-variables-between-js-and-sass)

Example:

```auto
// styles/animation.scss
$animation-length: 250;
$animation-length-ms: $animation-length + 0ms;

:export {
  animationMillis: $animation-length-ms;
}

```

Sonar CSS will report an error:  
`Unexpected unknown property "animationMillis"`

I can see a related closed issue [https://github.com/SonarSource/sonar-css/issues/149](https://github.com/SonarSource/sonar-css/issues/149) but I’m not sure to understand how to solve this false positive.
