Adding TranslateZoomRotateBehavior doesn't fire MouseLeftButtonUp

Question

I have an application which uses Expression Blend's TranslateZoomRotateBehavior which allows me to zoom or rotate my rectangle element.

After applying the said element, the existing MouseLeftButtonUp event won't trigger anymore when I am pinching the screen.

When I tried removing the element, MouseLeftButtonUp is working.

Is there a way that TranslateZoomRotateBehavior can coexist with MouseLeftButtonUp?

Please advise. Thank you.
