The Phabricator UI renders views (including this one) using the HTML5 doctype, and renders words inside backticks using the `<tt>` tag. <tt> is deprecated and is not part of the HTML5 markup spec: https://www.w3.org/TR/html5/
Steps to repro:
1. Inspect or view source on this page.
2. Find the doctype, and observe that it is <!DOCTYPE html>.
2. Find the "<tt>" string surrounded by backticks in the above paragraph, and observe that the generated markup is <tt class="remarkup-monospaced">.
Suggested fix: render strings inside backticks as `<code>foo</code>` instead of `<tt>foo</tt>`.
