Comment (by oldrup):

 Just pitching in. This is still a very real issue with PDF-files having
 transparent elements on the first page, apparently.. But, the "less
 elegant solution" mentioned by @thatstevensguy, still gets the job done,
 in WordPress 6.1

 I used "Force Regenerate Thumbnails" on those bulk selected existing PDF's
 in the media library with black backgrounds.

 The script handles new uploads too.

 A welcome patch! - but would be great if it wasn't needed.
