Numbered Attribute in Code listing causing invalid HTML

[christopappas]

Hello,

The 'numbered' attribute in code listings is causing trouble.

The asciidoc markup:

[[vagrantfile_minimal]]
.Minimal configuration for Vagrant

====
[source,ruby,numbered]
----
Vagrant.configure(2) do |config|
  config.vm.box = "data-science-toolbox/data-science-at-the-command-line"
end
----
====

The (invalid) htmlbook markup:

<pre data-type="programlisting" data-code-language="ruby"><table class="pyhltable"><tr><td class="linenos"><div class="linenodiv">1
2
3</div></td><td class="code"><span class="tok-no">Vagrant</span><span class="tok-o">.</span><span class="tok-n">configure</span><span class="tok-p">(</span><span class="tok-mi">2</span><span class="tok-p">)</span> <span class="tok-k">do</span> <span class="tok-o">|</span><span class="tok-n">config</span><span class="tok-o">|</span>
  <span class="tok-n">config</span><span class="tok-o">.</span><span class="tok-n">vm</span><span class="tok-o">.</span><span class="tok-n">box</span> <span class="tok-o">=</span> <span class="tok-s2">&quot;data-science-toolbox/data-science-at-the-command-line&quot;</span>
<span class="tok-k">end</span>
</td></tr></table></pre>
</div>

I'm having the same issue. Is there a way to add line numbers?
