Description

Steps to reproduce:
1. Compile and run:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark">

<s:layout>
<s:VerticalLayout />
</s:layout>

<s:Scroller horizontalScrollPolicy="on" verticalScrollPolicy="on" width="100%" height="100%">
<s:Group>
<s:Group width="100%">
<s:Button width="2000" />
</s:Group>
</s:Group>
</s:Scroller>

<s:Scroller horizontalScrollPolicy="on" verticalScrollPolicy="on" width="100%" height="100%">
<s:Group>
<s:SkinnableContainer width="100%">
<s:Button width="2000" />
</s:SkinnableContainer>
</s:Group>
</s:Scroller>

</s:Application>

2. Resize the application to see what the scrollbars do
3.

Actual Results:

The horizontal scroll bar is enabled as expected in the first Scroller, but doesn't work for the second Scroller.

The two Scrollers should look the same.
