Subject: [PATCH] Customize: Fix `nav_menu_item` CSS `classes` array being
 incorrectly presented in input field as comma-delimited list.

Instead of using `Array.toString()` to serialize an array with comma delimiters, explicitly `join` the array using spaces instead. Also ensure that `xfn` is handled properly if it ever gets stored as an array.

Props tyxla, westonruter.
Fixes #34111.
