Using IonicRouteStrategy causes angular ActivatedRoute queryParams observable not to fire

#1

Using ionic 4 with angular router, when the following provider is used in app.module.ts:

  providers: [
    ...
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
    ...
  ],

the ActivatedRoute queryParams observable will only fire once:

  constructor(
    ...
    private route: ActivatedRoute,
    ...
  }

  ngOnInit() {
    this.route
    .queryParams
    .subscribe((params: Params) => {
      // where reach here only once
      console.log('HomePage::queryParams', params);
    });
  }

However, the ActivatedRoute events observable will fire every time:

    this.router
    .events
    .pipe(filter(event => event instanceof NavigationEnd))
    .subscribe(event => {
      // will reach here
      console.log('NavigationEnd', event);
    });

Has anyone resolved this before?
