Gumbo CheckBox focus ring is around the entire box and label, not just the box

Steps to reproduce:
1. Run the following:
<?xml version="1.0" encoding="utf-8"?>
<Application xmlns="http://ns.adobe.com/mxml/2009" xmlns:mx="library:adobe/flex/halo" layout="flex.layout.BasicLayout">
<CheckBox label="New cb"/>
</Application>

2. Tab to the checkbox

Actual Results:
Focus ring is around the checkbox and the label

Expected Results:
Focus ring only around the checkbox. This is how it worked in Flex 3.

Workaround (if any):
