Code hints hint navigator.actionBar.addChild() but compiler complains and suggest addElement() which is not hinted

Steps to reproduce:
1. Create a Mobile Project with:
<?xml version="1.0" encoding="utf-8"?>
<s:ViewNavigatorApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
firstView="views.YourBugzHomeView"
creationComplete="viewnavigatorapplication1_creationCompleteHandler(event)">

<fx:Script>
<![CDATA[
import mx.events.FlexEvent;

import spark.components.Label;

protected function viewnavigatorapplication1_creationCompleteHandler(event:FlexEvent):void

]]
>
</fx:Script>

</s:ViewNavigatorApplication>

2. Compile

Actual Results:
Error: addChild() is not available in this class. Instead, use addElement() or modify the skin, if you have one.

• this is conflicting with the code hints which hint addChild() but not addElement().

Expected Results:
Compiler errors and code hints should reflect each other

Workaround (if any):
