Angular 9/10 not able to subscribe to both Params and Query Params. This was working in Angular 8 and less version

Question

 this.router.navigate(['/lp/flights/0'],{queryParams:{requestId : this.requestId}});

In app-routing.module.ts

{
    path: 'lp/flights/:destcode',
    loadChildren: () =>
      import(
        './ytb-modules/flight/flight-landing/flight-landing.module'
      ).then((m) => m.FlightLandingModule),
  },

Here , it is subscribing only to route params , and in the browser address bar only http://localhost:4200/lp/flights/0 is shown rather than http://localhost:4200/lp/flights/0?requestId=xxxx

queryParams is removed while router.navigate(), this behaviour was not there in Angular 8.
