[FlexJS] content being push out of the way in container

[Justin Mclean]

Hi,

I have this code:

<js:Container xmlns:fx="http://ns.adobe.com/mxml/2009"; 
xmlns:js="library://ns.apache.org/flexjs/basic”>
<js:Container id="cover" percentHeight="100" percentWidth="100" visible="false">
    <js:style>
        <js:SimpleCSSStyles backgroundColor="rgba(255,255,255,0.7)" />
    </js:style>
</js:Container>

<js:Label text=“Hello World" />
</js:Container>

Changing the visibility of the cover container causes the text to jump outside 
often container.

Oddly adding x=“0” y=“0” to the cover and the label fixes the issue. Should all 
items in a Container have x and y set to zero? It’s assume they overlap right? 
- unlike a HContainer or VContainer.

Thanks,
Justin
