Some feeds (typically rss feeds from invidious channels) have the
following structure for entries:
<item>
[...]
<content></content>
<description>A one line title</description>
<media:group>
[...]
<media:description>An actual text
that serves
as a description</media:description>
</media:group>
</item>
If it's there, and again longer than the other fields, use it
