label appears initially truncated when layout is specified in View

Steps to reproduce:
1. Create a mobile Flex project.
2. In a View, add ToggleSwitch.
3. Add any layout to the View:

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView">
<s:layout>
<s:VerticalLayout/>
</s:layout>
<s:ToggleSwitch />
</s:View>

4. Run the app.

Actual Results: "OFF" label renders as "O...". It will render correctly after re-loaded the view.

Expected Results: No label truncation.
