Problems testing observables that emit arrays or objects with other observables.

Bug Report

Current Behavior When using expectObservable to check an observable that emits and object with some observable the test fails.

Expected behavior The test should pass.

Reproduction That can be 100% reproduced using the code below.

• REPL or Repo link: https://replit.com/@fcostarodrigo/testSchedulerHighOrderObservables#index.test.js

const highOrderObj = of({ a: of('a') });

it('generate the stream correctly', () => {
  testScheduler.run(({ cold, expectObservable }) => {
    expectObservable(highOrderObj).toBe('(a|)', { a: { a: cold('(a|)') } });
  });
});

Environment

• Runtime: node v12.22.1
• RxJS version: 6.6.7

I'm not sure this is to be considered a bug, but maybe a feature request?

highOrderObj is a stream that emits objects - In a way I would expect for that to just deeply compare both objects (the expected and the result), but now one of the property of that object is an observable.

I'd like to have this feature, I think it makes sense. But I wouldn't consider it a bug

I was not sure as well if it was a bug or a feature. Since it works for of(of('a')) I was thinking it would be a bug. But working for of(of('a')) could be a coincidence.
