 In WPMU 2.8.4a (and possibly earlier versions), when logged in as a site
 admin to a blog that they aren't explicitly an administrator for, there is
 no "Post Author" dropdown field on the Edit Post or Edit Page screens.

 Steps to replicate:
 1. Login as a site admin to a blog that was created by another user (ie
 there is no wp_x_capabilities usermeta record for the site admin) for the
 corresponding blog id.
 2. Edit an exiting post or page.
 3. No "Post Author" or "Page Author" dropdown box is available, and there
 is no "Post Author" or "Page Author" option in the screen options section
 either.

 The problem is in the {{{get_editable_user_ids()}}} function in wp-
 admin/includes/user.php because the site admin doesn't have the
 {{{edit_others_posts}}}/{{{edit_others_pages}}} capability because the
 site admin doesn't actually have an administrator role.

 This results in an empty array being returned, which means that the author
 dropdown isn't displayed.

 In [1583], an {{{is_site_admin()}}} check was added to the
 {{{current_user_can()}}} function. Perhaps a similar check needs to be
 added to the {{{WP_User::has_cap()}}} function?
