rxjs-marbles testing has no expectations

I use rxjs-marbles for testing observables in my Angular 7 app. But it looks like m.expect is not recognized by jasmine as expectation.

I have following test:

it('should see expectations', marbles(m => {

  const source: Observable<Message> = m.hot('^a--b--c');

  m.expect(source).toBeObservable('-a--b--c');

}));

When I run it I get error in console:

ERROR: 'Spec 'FeatureFlagsService should see expectations' has no expectations.'

Also in browser output my test is prefixed with:

SPEC HAS NO EXPECTATIONS should see expectations

Adding expect(true).toBe(true); fixes the issue but this is not really way I want to go.

How to register m.expect as a expectation for jasmine?
