馃悶 bug report

Is this a regression?

Not sure.

Description

Component:

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  value: {a?: {v: number}, b?: {v: number}} = {b: {v: 123}};
}

Code

<!-- This will fail: Object is possibly 'undefined'-->
<p *ngIf="value.b">{{value.a.v}}</p>

<!-- But this will not :( -->
<p *ngIf="value.b">
  {value.a.v, plural, other {...}}.
</p>

Expected behavior:

Both examples must fail with the message "Object is possibly 'undefined'".

Actual behavior:

No errors for {value.a.v, plural, other {...}}.
