How to remove WebStorm sass-lint error "Unknown pseudo selector 'ng-deep'" : <p>Angular 2+ with scss and ::ng-deep in WebStorm highlights this selector with text "Unknown pseudo selector 'ng-deep'"</p>

<p>I tried something like:</p>

<pre><code>selector-pseudo-class-no-unknown: true
  ignorePseudoClasses: ng-deep

or

selector-pseudo-class-no-unknown: false
</code></pre>

<p>None of this works.</p>

<p>How to set exception in scss-lint.yml for this pseudo-selectors?</p>
