Component rerender even though property did not change

In my Ember app I recognized performance issues and found out that my components are rerendered even though the property did not change.

The component has only one attribute which is a computed property. The dependent value of the computed property did change but the result of the computed property is still the same. Therefore I thought that the component does not detect an attribute change.

As an example I created a short Ember Twiddle: Ember Twiddle

Is this behavior intentionally or do I misinterprete something?
