DropShadowEnabled no longer supported in Flex Hero build 17689

Question

Hi,
I am using the latest "nightly" Flex 4.5  SDK, build 17689.  It seems the dropShadowEnabled property is no longer  supported with the Hero default skin.  I get this compilation error:
The style 'dropShadowVisible' is only   supported by type   'spark.components.Panel' with the   theme(s) 'spark'.
Is there any way to disable the shadow without making a custom panel skin?  Now I have shadows on top of shadows as I use panels within other panels, and shadows where I do not need/want them.
Thanks.

@Alon K.,
When you say "no longer supported", were you seeing this work in earlier builds when using the Spark Panel and Halo theme?
I tried this code w/ Flex 4.0 and the Halo theme and saw the same error (which I believe is the correct behavior since I'm using the Halo theme but that style is only supported by the Spark theme):
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

               xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:Panel id="pnl"
             title="Spark Panel title"
             dropShadowVisible="{ch.selected}"
             width="300" height="150"
             horizontalCenter="0" verticalCenter="0">
        <s:Label text="Content area" width="100%" backgroundColor="red" />
        <s:controlBarContent>
            <s:CheckBox id="ch" selected="true" />
        </s:controlBarContent>
    </s:Panel>
</s:Application>
