The update() method in wrappinglayout class does not skip invisible subviews.
This behaves differently with the update() method in simplelayout class.

If this is confirmed as a bug, the following extra check may be used to fix this bug:

BEFORE:
   <method name="update">
        <![CDATA[
 .....
        for(var i=0; i < l; i++) {
            var s = this.subviews[i];
            s.animate(this.axis, pos, this.duration,false);
....

AFTER:
...
        for(var i=0; i < l; i++) {
            var s = this.subviews[i];
            if ( !s.visible ) continue; //add visibility check before procesing a subview
            s.animate(this.axis, pos, this.duration,false);
.....


thank you.
