CAP does not filter the byline that is output for posts via oEmbed; oEmbed consumers show the wrong byline

Here's a test post by a WP_User:

{
  "version": "1.0",
  "provider_name": "largo.test",
  "provider_url": "https://largo.test",
  "author_name": "WP Snapshots WP_User",
  "author_url": "https://largo.test/author/wpsnapshots/",
  "title": "Post by WP_User",
  "type": "rich",
....

And here's a test post by a Coauthor:

{
  "version": "1.0",
  "provider_name": "largo.test",
  "provider_url": "https://largo.test",
  "author_name": "WP Snapshots WP_User",
  "author_url": "https://largo.test/author/wpsnapshots/",
  "title": "Post by Guest Author",
  "type": "rich",
....
