Is this a regression?

Yes, the previous version in which this bug was not present was: 7.3.2

Description

The fix for #13689 now generates a second comma between styleUrls and encapsulation. The comma behind styleUrls is now also present if the flag --viewEncapsulation is not set at all and styleUrls is the last property.

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],, // ❗ duplicate comma
  encapsulation: ViewEncapsulation.Native
})
export class AppComponent {
}

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'], // ❗ unnecessary comma
})
export class AppComponent {
}

🔬 Minimal Reproduction

• ng new view-test --skipGit --skipInstall --viewEncapsulation None
• ng new view-test --skipGit --skipInstall

🔥 Exception or Error

ERROR in src/app/app.component.ts(6,38): error TS1136: Property assignment expected.
