Parser not parsing all fields on (some?) Podcasts?

For certain podcasts, such as: https://rss.art19.com/id10t

When calling FeedParser.parse or using a concrete parser, the resulting ParsedFeed has nil fields, such as feedDescription.

I also tried with the Joe Rogan Podcast: joeroganexp.joerogan.libsynpro.com/rss
