Submenu class 'menu-item-has-children' stopped working

[fpodhorsky]

Hello,
I don't know, maybe I am wrong, but when I updated to v6.1 I have noticed, that submenu stopped working and the class 'menu-item-has-children' was missing. So I started debugging and I found out that in wp-includes/nav-menu-template.php - function wp_nav_menu() was weird if statement.

<?php
// Add the menu-item-has-children class where applicable.
    if ($menu_items_with_children) {
        foreach ($sorted_menu_items as &$menu_item) {
            if (
                isset($menu_items_with_children[$menu_item->ID]) &&
                ($args->depth <= 0 || $menu_items_with_children[$menu_item->ID] < $args->depth)
            ) {
                $menu_item->classes[] = 'menu-item-has-children';
            }
        }
    }

The part where is "$args->depth <= 0" should probably look like this - "$args->depth >= 0", because the argument depth must be higher or the same as 0 to have submenu.

Thank you for checking and I am sorry if I am wrong.
Please, excuse my English.

I am also seeing this issue. It happends when "depth" attribute is set. Unsetting the depth attribute remediates the issue.

Yes, that's the solution for now. Good to hear that I am not the only one having this problem.
