CSS type selectors are not supported in components ?

Question

If I put an <mx:Style> section in an MXML-based
component, I get a number of warnings stating
CSS type selectors are not supported in components. That
said, the styles appear to actually work, and I'd sure
like them to work. Is this a bug in the compiler, or is this
truly not supported?

Hi!
I have the same problem when I apply a style to a Panel, I have a Canvas component and contains a Panel inside, but I fail to apply the css.
I call the css from the main file main.mxml, but when I load the component will give a warning message and does not apply the style. "CSS type selectors are not supported in components: 'Panel' "
This is file main.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
      xmlns:comp="components.*" backgroundAlpha="0" horizontalScrollPolicy="off">
     <mx:LinkBar dataProvider="myComp" horizontalCenter="0" y="380"/>
     <mx:ViewStack id="myComp" horizontalCenter="0" resizeToContent="true">
           <comp:component_01 height="100%" width="85%" label="HOME"/>
           <comp:component_02 height="100%" width="85%" label="GALLERY"/>
           <comp:component_03 height="100%" width="85%" label="TECHNOLOGY"/>
      </mx:ViewStack>
     <mx:Style source="skin_prototype02.css"/>
</mx:Application>
File component_02.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%">
      <mx:Panel title="Photo gallery" x="10" y="10" width="575"
            horizontalScrollPolicy="off"> 
      </mx:Panel>
</mx:Canvas>
