noscript output seems to break sometimes when using Commonmark

[0xdevalias]

This plugin seems to break it's output when attempting to embed the following gist when noscript is enabled, and jekyll-commonmark is used as the markdown renderer

• https://gist.github.com/0xdevalias/e8bb28726a37854606ad
• embedded into a blog post with {% gist 0xdevalias/e8bb28726a37854606ad %}

_config.yml

markdown: CommonMark

commonmark:
  options: ["UNSAFE", "FOOTNOTES", "STRIKETHROUGH_DOUBLE_TILDE", "VALIDATE_UTF8", "GITHUB_PRE_LANG", "HARDBREAKS"]
  extensions: ["autolink", "strikethrough", "table", "tasklist"]

  return &amp;quot;I drew a cat!&amp;quot;

```&lt;/pre&gt;&lt;/noscript&gt;&lt;script src=&quot;https://gist.github.com/0xdevalias/e8bb28726a37854606ad.js&quot;&gt; &lt;/script&gt;
</code></pre>

In particular, the end part of the rendered noscript seems to be getting itself confused, and then ends up breaking the output:

```</pre></noscript><script src="https://gist.github.com/0xdevalias/e8bb28726a37854606ad.js"> </script>
</code></pre>

This doesn't appear to happen on other posts where I have gists embedded.

My theory is that maybe because the gist ends in a triple backtick codeblock (possibly with no newline?), that that may be breaking something within this plugin, that then flows on to breaking how commonmark parses/renders things?
