[jlreq] Double-sided ruby not displayed correctly (#176)

r12a has just created a new issue for https://github.com/w3c/jlreq:

== Double-sided ruby not displayed correctly ==
In order to get double-sided ruby to appear on either side of the base text in HTML, you need the CSS <code class="kw" translate="no">ruby-position</code> property to work with the value <code class="kw" translate="no">under</code>. It currently works per the standard only with <span class="pass">Firefox</span>. It works with the proprietary<code class="kw" translate="no"> -webkit</code> prefix in <span class="partial">Chrome</span> and <span class="partial">Safari</span>, but doesn't work with <span class="fail">Edge</span>. <a href="https://w3c.github.io/i18n-tests/results/css-ruby#ruby_position">See test results</a>.

Double-sided ruby doesn't appear often in Japanese text, but it is used, and should be available to content authors.
