Button borders not showing when using the WP8.1 version

[JogyBlack]

I am developing an universal app and I tried to use the rate control. But when it shows, the "rate" and "no thanks" buttons do not have a border.

After digging a bit in the sources, I discovered that the buttons have bindings like this:

BorderBrush="{Binding Foreground, ElementName=RmaControl}"

but the "RmaControl" name is not defined. Setting the name of the containing UserControl to "RmaControl" fixed the issue for me,
