 Line 4276 in taxonomy.php can return a WP_Error object, which is not
 checked before calling wp_list_pluck().

 Result is a fatal error:

 Fatal error: Cannot use object of type WP_Error as array in /wp-
 includes/functions.php on line 3511

 The code should pass the WP_Error object to the calling function.
