ngClass fails to update class when initial value is `false`

Minimal repro case:

We'd like to set a class on an element by default, and then have it removed by Angular on bootstrap (assuming the expression for that particular class evaluates to false).

Our workaround for now is to just reverse the behavior so that you need to add a class to get the desired effect. Angular updates class correctly when the initial value is true.

OMG, this is really a corner case :-) But kind of valid bug anyway... Here is a test:

it('should remove classes', inject(function($rootScope, $compile) {
    element = $compile('<div class="red" ng-class="{red: false}"></div>')($rootScope);
    $rootScope.$digest();
    expect(element[0].className).toBe('');
  }));

There seems to be a PR for that #9811

Oh, @Narretz how are you finding those references? Whatever you do you are good at it :-)
I will take a look at the patch.

@pkozlowski-opensource Just a good memory :)
