How to remove WebStorm sass-lint error "Unknown pseudo selector 'ng-deep'"

::ng-deep is pseudo element, not pseudo class. This is equivalent in my .stylelintrc

{
  "rules": {
    "selector-pseudo-element-no-unknown": [true, {
      "ignorePseudoElements": ["ng-deep"]
    }]
  }
}

Also you need to uncheck Settings -> Inspections -> CSS -> Invalid Elements -> Invalid CSS pseudo selector
