Flex bug in global error handling

Question

My application's global error handler (uncaught error handler) works mostly, but I found a case where it doesn't work, but should.  Before I filed an official bug report I wanted to post the issue here.
Here is the issue: in a module, ErrorEvents that are not listened for  and are dispatched by a Flex component are never caught in the application's uncaught error handler. 
I have a sample project that demonstrates this.  Here is the module in my test case:
<?xml version="1.0" encoding="utf-8"?>
<s:Module xmlns:fx="http://ns.adobe.com/mxml/2009"
             xmlns:s="library://ns.adobe.com/flex/spark"
             xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
    <![CDATA[
        private function onClickSparkDispatch():void {
            dispatchEvent( new ErrorEvent( ErrorEvent.ERROR, false, false, "test" ) );   // this isn't caught in the uncaught error handler
        private function onClickNonSparkDispatch():void {
            var nonSparkDispatcher:EventDispatcher = new EventDispatcher();
            nonSparkDispatcher.dispatchEvent( new ErrorEvent( ErrorEvent.ERROR, false, false, "test" ) );  // this is caught in the uncaught error handler
    ]]>
</fx:Script>   
    <s:HGroup>
        <s:Button label="Module Spark Dispatch (broken)" click="onClickSparkDispatch()" />
        <s:Button label="Module Non-Spark Dispatch" click="onClickNonSparkDispatch()" />
    </s:HGroup>
</s:Module>
Using Flex 4.6
My application statically links in the Flex SDK ("merged into code" in Flash Builder).
My applications works around these two exsiting bugs:

Is this a bug?
Thanks,
