<p>Animations that animate the same property but are of a different type aren't stopped when a new animation is started.</p>

<p>E.g. a DoubleAnimation that animates a RenderTransform.X isn't stopped if a DoubleAnimationUsingKeyframes is started that animates the same property. Everything seems to work correctly if both animations are of the same type.</p>
