Actuate - autoVisible not working

Hi,

i just noticed that the Actuate tween.autoVisible (false); is not toggling the visibility of the the object.

Actuate.tween(btnNext, 0.4, {alpha:0}).autoVisible(false).ease(Sine.easeOut);

The behavior should be as follows:

var sprite = new Sprite ();

Actuate.tween (sprite, 1, { alpha: 0 }).autoVisible (true); // default

// over one second, the alpha fades to zero. at the end, visible is set to false
var sprite = new Sprite ();

Actuate.tween (sprite, 1, { alpha: 0 }).autoVisible (false);

// over one second, the alpha fades to zero. sprite.visible stays true
