For reasons beyond my ability to solve, my #footer-wrapper is inheriting a height of 0px, and causing a display issue. The height issue resolves when the first tier of media queries kick in. Nowhere in my CSS (that I can see?) is this specified. Any help solving this problem would be greatly appreciated. For what it's worth, the error did not starting taking place until the most recent Responsive theme update (18.104.22.168).
