Show notes cut off mid-tag give way to the item's description

libsyn served Daily Meditation Podcast's content:encoded cut at the '>'
inside a Tailwind class pasted from a web app, so 57 items began halfway
through a tag and the page showed the rest of it as text. Their
description was whole. A body that closes an attribute list before any
tag opens now falls back to the description, for RSS and Atom alike.
