escaped html tag in entry title is stripped

[codl]

The most recent entry in https://jakearchibald.com/posts.rss is titled "How should <selectedoption> work?", escaped in the feed as:

    <title type="html"><![CDATA[How should &lt;selectedoption&gt; work?]]></title>

However miniflux 2.2.3 displays it as "How should work?". The tag is entirely stripped, it's not present in the rendered miniflux page.
