Some feeds, like that of Diigo [https://www.diigo.com/rss/user/Agharbeia ] erroneously includes HTML markup in the <description> element of RSS. In this specific case they use it to encode tags/keywords of bookmark items, where they should be using the <category> element for that. The HTML markup causes havoc in the wikipage and editor. It's better to sanitise content of <description>, and probably other elements, before emitting them to the page.
