Angular e2e Testacular Test: How To Tell Visibility?

Question

Has anyone successfully tested if a Bootstrap Modal is displayed when a button is clicked?

Details

I am writing a Testacular test that checks to see if a Bootstrap modal is displayed when a button is clicked. The problem is that the call to css('display') returns 'none' even though I can see that the window pops up and is visible.

I'm wondering if there's something kooky going on with the Bootstrap Modal that duplicates a block of html then displays that with a different id. I certainly hope not!

Code

The scenario

describe('e2e', function() {

  beforeEach(function() {
    browser().navigateTo('/chessClub/');
  });


  it('should display editor when add member button clicked', function() {
    expect(element('title').text()).toBe("Chess Club");

      expect(element('#myModal').css('display')).toBe('none'); //as expected, it is none
              //click the button to show the modal
      element('#addMemberButton','Add Member Button').click();

              //this 2nd expect still return 'none'
      expect(element('#myModal').css('display')).toBe('block');

  });

});

test output

Chrome 25.0 e2e should display editor when add member button clicked FAILED
    expect element '#myModal' get css 'display' toBe "block"
    /Users/jgordon/learning/chessClub/web-app/test/e2e/scenarios.js:17:4: expected "block" but was "none"
