DropDownList goodness when enabled set to true on change

Steps to reproduce:
1. Set up an app with 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"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<s:DropDownList id="dropDown" y="500" change="

">
<s:dataProvider>
<s:ArrayList>
<fx:String>Test 1</fx:String>
<fx:String>Test 2</fx:String>
</s:ArrayList>
</s:dataProvider>
</s:DropDownList>
</s:Application>

2. Click the drop-down list.
3. Select an item from the list.

Actual Results:

The drop-down list doesn't go away. The drop-down list loses a lot of its functionality.

Expected Results:

The item should be selected and the drop-down list should go away.

Workaround (if any):

Don't set enabled to true on change.
