**WHEN** I use custom `ngDoBootstrap` function instead of default `bootstrap: [AppComponent]` like this:

```
@NgModule({
  imports:      [ BrowserModule, FormsModule, AppRoutingModule ],
  declarations: [ AppComponent, HelloComponent ],
  exports: [ AppComponent ],
  entryComponents: [ AppComponent ],
  // bootstrap: [AppComponent],
})
export class AppModule {
  constructor(private injector: Injector) {
  }

  public ngDoBootstrap(): any {
    const appElement = createCustomElement(AppComponent, { injector: this.injector });
    customElements.define('my-app', appElement);
  }
}

```

**THEN** 
Application routing is broken.

It ignores any changes in the URL and only works when I click on `<a [routerLink]='...'>`. Also the initial route / is not loaded.

It must be caused by the custom bootstrap mechanizm, because when I uncomment the `bootstrap: [AppComponent]`, everything works fine.

Full code is available here: [stackblitz sample](https://stackblitz.com/edit/angular-customelements-routing?file=src%2Fapp%2Fapp.module.ts) (needs to be downloaded and run locally because of typescript version used by stackblitz)

How to make the routing work with custom app module bootstrapping?
