Compiler does not respect the implements="..." attribute in MXML

It seems that there is a bug where the compiler does not respect the implements="..." attribute in MXML.

MXML Example:
<!-- MyInitialView.mxml -->
<js:ViewBase xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:js="library://ns.apache.org/flexjs/basic"
implements="com.demo.core.interfaces.IViewMyInitialView">
</js:ViewBase>

That information is not being included in the MyInitialView.js output:

MyInitialView.prototype.FLEXJS_CLASS_INFO = { names: [

] };
