<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Menus: Convert `wp_get_nav_menu_items` function to use a taxonomy query.
Change the `wp_get_nav_menu_items` function to replace the call to `get_objects_in_term` with a simple taxonomy query. This change improves performance as it results in one fewer query to retrieve menu items from the
database.
