Reset broadcast() after each test case while using andCallThrough()

I am using the code bellow to reset $broadcast after each test case, but it seems it $rootScope.$broadcast.reset(); doesn't function properly, since the test bellow should return 1, but it returns 6.

Seems that the reason for this is andCallThrough(), since before I used it without andCallThrough() function, but after some refactor it gave me an error that TypeError: Cannot read property 'defaultPrevented' of undefined, so I had to use to prevent that error.

The question is how can i reset the broadcast while using andCallThrough or is there another more precise approach?

beforeEach(function() {
   spyOn($http, 'post');
   spyOn($rootScope, '$broadcast').andCallThrough();
});

afterEach(function() {
   $http.post.reset();
   $rootScope.$broadcast.reset();
});

it('should make a POST request to API endpoint', function() {
   $http.post.andCallThrough();
   var response = { id: '123', role: 'employee', email: 'user@email.com', username: 'someUsername' };
   $httpBackend.expectPOST(apiUrl + 'login').respond(response);
   service.login();
   $httpBackend.flush();
   $timeout.flush();
   expect($rootScope.$broadcast.callCount).toBe(1);
   expect($rootScope.$broadcast).toHaveBeenCalledWith(AUTH_EVENTS.loginSuccess, response);
});
