 In WordPress 5.9 in the classic editor when editing a post, the “Author”
 pulldown only shows the administrators. In 5.8.3 it listed all of the
 authors (and contributors). Here’s the screenshot from 5.9 when using the
 classic editor: https://photos.app.goo.gl/zQjK441TmNKL2wJf9
 It still shows all the authors (in 5.9) when I switch to the block editor.
 Here’s the screenshot using 5.9 with the block editor:

 In 5.8.3 it lists all of the Authors in the Author dropdown when using the
 classic editor:

 It looks like this was due to a change in the function
 post_author_meta_box in the file src/wp-admin/includes/meta-boxes.php
 It used to display all of the authors and contributors regardless of their
 capabilities and now it only displays users that have the "edit_posts"
 capability.

 Here's the commit that introduced the problem:
