rxjs/no-exposed-subjects rule doesn't work properly

Problem

Hello! Facing a strange behavior of no-exposed-subjects rule, as I recently read in docs "Disallows exposed subjects. In classes, Subject properties and methods that return a Subject must be private.", so I guess eslint must notify me about three errors if I will write this:

@Component({
  selector: 'app-component',
  ....
})
export class AppComponent {
   public foo$: Subject<unknown>;

   public bar$ = new Subject<unknown>();

   public getFoo(): Subject<unknown> {
     return this.foo$;
   }
}

But it marks as error only public "getFoo" method that returns public Subject. I expected public bar$ = new Subject<unknown>(); and public foo$: Subject<unknown>; are wrong too. Can someone explain this situation? Thanks a lot!
