Button / Label overlap inside form.

Created by: thealch3m1st

I was looking at Bootstrap 3 RC1 on the website (http://twitter.github.io/bootstrap/css/) and I noticed a button overlaps a label inside a form. I'm using Safari 6.0.5 (8536.30.1) on a 15" Retina MacBook Pro running 10.8.4. This doesn't happen in Chrome (Version 28.0.1500.71) on the same machine.
