Steps to reproduce:
1. Create a new Flex mobile project with this list:
<s:List height="100%" width="100%" id="itemList" pageScrollingEnabled="true">
<s:itemRenderer>
<fx:Component>
<s:IconItemRenderer width="100%" height="100%" labelField="imageName" messageField="imageDesc" />
</fx:Component>
</s:itemRenderer>
<s:layout>
<s:VerticalLayout verticalScrollPosition="

{itemList.dataGroup.height*2}

" gap="100" variableRowHeight="false"/>
</s:layout>
<s:dataProvider>
<s:ArrayList>
<fx:Object imageIcon="assets/Chrysanthemum.jpg" imageDesc="Chrysanthemum" imageName="Chrysanthemum" />
<fx:Object imageIcon="assets/Desert.jpg" imageDesc="Desert" imageName="Desert" />
<fx:Object imageIcon="assets/Hydrangeas.jpg" imageDesc="Hydrangeas" imageName="Hydrangeas" />
<fx:Object imageIcon="assets/Jellyfish.jpg" imageDesc="Jellyfish" imageName="Jellyfish" />
<fx:Object imageIcon="assets/Koala.jpg" imageDesc="Chrysanthemum" imageName="Chrysanthemum" />
<fx:Object imageIcon="assets/Lighthouse.jpg" imageDesc="Koala" imageName="Koala" />
<fx:Object imageIcon="assets/Tulips.jpg" imageDesc="Tulips" imageName="Tulips" />
<fx:Object imageIcon="assets/Penguins.jpg" imageDesc="Penguins" imageName="Penguins" />
</s:ArrayList>
</s:dataProvider>
</s:List>
