Comment (by uz01):

 The wp_list_pluck function in WordPress triggers a PHP warning when trying
 to access a non-existent key in an array. This warning can clutter logs
 and cause confusion.

 Proposed Solution: Use the isset() function to check if a key exists
 before accessing it. This avoids the PHP warning by assigning an empty
 array if the key is missing.

 Environment: WordPress 6.3+, PHP 8+, Ubuntu.

 This change makes the function more robust and prevents unnecessary
 errors.
