 I've trying to force myself to use PHP 8.2 to get our plugins into shape,
 but am still running into a deprecation notice in post.php when viewing
 the Media Library in list mode:

 {{{
 PHP Deprecated: preg_match(): Passing null to parameter #2 ($subject) of
 type string is deprecated in /sites/test.example.com/files/wp-
 includes/post.php on line 3298
 }}}

 Checking if $real is true before preg_match() is run seems to fix this
 particular one, but maybe to be safe an is_string( $real ) should be run
 also?
