Bug description

Probably the OG:description is not working.

I often include Mastodon's or Misskey's post URLs in my posts. Then I noticed that the body of Misskey's post had not been expanded.

I've heard from Misskey users that they have an OG:description. After that exchange, @kPherox examined the source code for me. The result is that it doesn't seem to expand the description when the twitter:card is included.

Card-expanded example of a Misskey post: https://pl.komittee.net/notice/9vcmn2otYcDazbP6Ia

https://git.pleroma.social/pleroma/pleroma/-/blob/develop/lib/pleroma/web/rich_media/parsers/meta_tags_parser.ex#L39-53

In the case of Mastodon and Pleroma's posts, the text is transcribed in the title, so there is (fortunately) no effect of card expansion.
