Summary: KaTeX doesn't work correctly in quirks mode. Warn in the console and disable rendering if that happens. Test Plan: - Make sure the test still loads and renders math - Make sure a warning is thrown when the doctype is removed, and no more math is rendered - Make sure the tests pass both on the web and with `make test` Reviewers: alpert Reviewed By: alpert Differential Revision: http://phabricator.khanacademy.org/D13192
