Animation start is delayed when used inside a behavior bound to another animated property

The test case attached shows the problem, both animations should progress simultaneously, but, instead, the animation inside the behavior only gets triggered when the other one finishes.

From my debugs, the animation framework is doing the right thing. The problem is that Behavior is stopping the qtAnimation everytime there is a property change (in this example at each tick), which prevents the animation in the behavior to progress.

This use case is important in order to turn EaseFollow into an animation.
