How to write inheritance with stimulus controller ?

See original GitHub issue

// javascript/packs/controllers/parent_controller.js
import { Controller } from "stimulus"
export class ParentController extends Controller {
  myParentFunction(){
  }
}

// javascript/packes/controllers/child_controller.js
import { ParentController } from "parent_controller.js"
export default class extends ParentController {
  connect(){
    console.log("child controller loaded!")
  }    
}

I have this error:

Uncaught TypeError: Super expression must either be null or a function, not object

}
