Quick summary

With Twenty Twelve, when we add a Buttons block and try to change the color options, it doesn't get applied despite having the right classes.

I'm reporting this here as Block widgets appear to be specific to .com.

Steps to reproduce

1. Activate Twenty Twelve
2. Add a button block
3. Try to change the colors(text/background) of the buttons block
