( 1.2.0 ) ngShow and class attribute with expression don't work together

[raeno]

Hello, I've found a problem with a Angular 1.2.0
ng-hide class is omitted when tag contains ngShow directive and class attribute with angular expression inside:

  <div ng-show="divId == 1" class="{{additionalClass}}">Div 1</div>

When 'additionalClass' value is updated in controller - element is shown no matter what ng-show value currently is.
I made a plunker that shows this problem:

Tested it with 1.0.8, works without any problems.
