Error: NG0203 when using inject() in abstract base class member

[Stephan Kaneman]

Is this a regression?

No

Description

I have a abstract base class with a member implementation that uses Angular 14+ inject() method to get the value for an injection token;

export abstract class SomeBaseService {
  protected readonly someMember: MyType = inject(MY_TOKEN);

Injectable()
export class ConcreteService extends SomeBaseService {
}

This throws an error when using with Spectator :

const createService = createServiceFactory({
    service: ConcreteService ,
    providers: [{ provide: MY_TOKEN, useValue: myValue}],
  });

beforeEach(() => (spectator = createService()));

Please provide a link to a minimal reproduction of the bug

Does it work with plain Angular?
