Description

Steps to reproduce:
1. Run the following application
<?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">

<fx:Script>
<![CDATA[
protected function button1_clickHandler(event:MouseEvent):void

{ listData.removeItemAt(list.selectedIndex); }

]]
>
</fx:Script>

<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

<s:layout>
<s:VerticalLayout />
</s:layout>

<s:List id="list" width="100%" requireSelection="true">
<s:dataProvider>
<s:ArrayList id="listData">
<fx:String>Item 1</fx:String>
<fx:String>Item 1</fx:String>
<fx:String>Item 1</fx:String>
<fx:String>Item 1</fx:String>
</s:ArrayList>
</s:dataProvider>
</s:List>

<s:Button label="Delete Selected Item" click="button1_clickHandler(event)"/>
</s:Application>

2. Select the last item in the list
3. Press the delete button
4. Click on the first item in the list

Actual Results:
The first item briefly highlights and then deselects

Expected Results:
There seems to be two bugs here. I would expect the following:
1) After deleting the item, another item should be selected since requireSelection is true
2) After deleting the item, i should be able to click on all the other renderers

Workaround (if any):
