While testing 5.9 RC1 I found that the font family selection for paragraphs was not yet available. @carolinan and @bph mentioned the issue #37586, however, it was discussed to revert that feature as the Webfont API is not ready yet, so it got removed with PR #37815.

While further testing I noticed that it is still in use by several blocks and to avoid unneccessary confusion in 5.9, I'd suggest to have it removed from those blocks as well:

• List
• Button
• Verse
• Navigation
• Post Title
• Archive Title
• Website Title
• Website Tagline
