Cannot select items in Spark DropDownList in Mobile Project

Steps to reproduce:

1. Create a FlexMobile Project

2. Paste the following code

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
creationComplete="init()">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;

public var testColl : ArrayCollection = new ArrayCollection(["one","two","three"]);

public function init():void

{ ddl1.dataProvider = testColl; ddl2.dataProvider = testColl; ddl2.selectedIndex = 2; ddl3.dataProvider = testColl; ddl3.typicalItem = testColl[0]; }

]]
>
</fx:Script>
<s:VGroup>
<s:DropDownList id="ddl1"/>
<s:DropDownList id="ddl2"/>
<s:DropDownList id="ddl3"/>

<!-- from http://help.adobe.com/en_US/flex/using/WSc2368ca491e3ff92-59bf082612135c9e688-7fff.html also broken-->
<s:DropDownList width="140">
<s:ArrayCollection>
<fx:String>Alabama</fx:String>
<fx:String>Alaska</fx:String>
<fx:String>Arizona</fx:String>
<fx:String>Arkansas</fx:String>
<fx:String>California</fx:String>
</s:ArrayCollection>
</s:DropDownList>
</s:VGroup>

</s:Application>

3. Debug either on the desktop (e.g. as an Android phone) or on the device, it doesn't matter which.

Actual Results:

In all cases, you can open the drop down but can't select anything with the mouse. Using the keyboard works.
Touch does not work to select items.

Expected Results:

It should work.

Workaround (if any):

None found.
