<p>How about an empty code block?</p>
<pre><code class="language-js"></code></pre>
<p>How about a code block with only an empty line?</p>
<pre><code class="language-js">
</code></pre>

<p>With some trailing empty lines:</p>
<pre><code>ciao


</code></pre>

<p>Closing fences must lay on a new line:</p>
<pre><code>hello()
^```
&quot;this should still be in the code block!&quot;</code></pre>
