Footer HTML requested from the branding API was including two CSS files, lms-footer.css and lms-footer-edx.css. edx.org pages only require lms-footer-edx.css to render the footer. The template code being removed here appears to have been accidentally left in place during a theming change: c0648ab164\#diff-439477a9ba29f7c208e25b0a535cdabeR80.
