Resize + percentHeight = wacky

Code:

<?xml version="1.0" encoding="utf-8"?>
<mx:application mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:script>
<![CDATA[

//these don't work with resize effect

b.percentHeight = 20;
a.percentHeight = 80;

b.percentHeight = 80;
}
//these DO work with resize effect
private function a2():void{
b.height = v.height * 0.2;

}
private function b2():void{
a.height = v.height * 0.2;

<!--
Run as is, with click functions a1 and b1, to see what goes wrong with resizing with a Resize object and percent heights.
(It's a doozy.)
Then change click functions to a2 and b2 to see how it is done right (rightly?).
Note, a1 and b1 work just fine if no Resize object is used.
