[FLEX-22902] UIComponent.scaleX, scaleY differ from transform.matrix.a,d

Description

Steps to reproduce:
private function testScale():void

{ var obj:DisplayObject = new mx.core.UIComponent; var tm:Matrix = new Matrix(); tm.scale(20,20); obj.transform.matrix = tm; trace("obj="+obj+" obj.transform.maxtrix.a="+ obj.transform.matrix.a+ " obj.scaleX="+obj.scaleX); obj.scaleX = 25; obj.transform.matrix = new Matrix; trace("obj="+obj+" obj.transform.maxtrix.a="+ obj.transform.matrix.a+ " obj.scaleX="+obj.scaleX); }

Actual Results:
obj=UIComponent148 obj.transform.maxtrix.a=20 obj.scaleX=1
obj=UIComponent148 obj.transform.maxtrix.a=1 obj.scaleX=25

Expected Results:
obj=UIComponent148 obj.transform.maxtrix.a=20 obj.scaleX=20
obj=UIComponent148 obj.transform.maxtrix.a=1 obj.scaleX=1

works correctly (as "expected") for other (non-UIComponent) DisplayObjects like Sprite, Bitmap.

Workaround (if any):
directly set scaleX when doing matrix operations,
or only use scaleX and do not use matrix ops...
