Please describe your bug.

When using the amplify-authenticator component inside a component with ChangeDetectionStrategy.OnPush, nothing is rendered.

What's the expected behaviour?

The amplify-authenticator component should take care of change detection on its own.

Help us reproduce the bug!

I've setup a sample repository : https://github.com/QuentinFchx/amplify-ui-change-detection

When you serve the project, you should see a blank page : the amplify-authenticator is not rendered.

As a workaround, you can uncomment the following lines at https://github.com/QuentinFchx/amplify-ui-change-detection/blob/main/src/app/app.component.ts#L24

this.unsubscribe = this.authenticator.subscribe(() => {
    this.cdRef.detectChanges();
}).unsubscribe;

AFAIK, the issue seems to come from https://github.com/aws-amplify/amplify-ui/blob/main/packages/angular/projects/ui-angular/src/lib/components/authenticator/components/authenticator/authenticator.component.ts#L89.
I'm not sure what is the purpose of the hubSubject, but the callback is never called, thus :

• the detectChanges in the callback is never called
• isHandlingHubEvent is never set to true, thus the detectChanges of the authenticator subscription (a few lines below) is never called
