Menu Item Depth calculation logic is not correct

[moha12351]

I have checked the WordPress core wp-includes/nav-menu-template.php file and found some issues in the menu item depth calculation login

Current code from lines 201 to 216

  foreach ( (array) $menu_items as $menu_item ) {
		$sorted_menu_items[ $menu_item->menu_order ] = $menu_item;
		$menu_items_tree[ $menu_item->ID ]           = $menu_item->menu_item_parent;
		if ( $menu_item->menu_item_parent ) {
			$menu_items_with_children[ $menu_item->menu_item_parent ] = 1;
		}

		// Calculate the depth of each menu item with children
		foreach ( $menu_items_with_children as $menu_item_key => &$menu_item_depth ) {
			$menu_item_parent = $menu_items_tree[ $menu_item_key ];
			while ( $menu_item_parent ) {
				$menu_item_depth  = $menu_item_depth + 1;
				$menu_item_parent = $menu_items_tree[ $menu_item_parent ];
			}
		}
	}

My Solution

foreach ( (array) $menu_items as $menu_item ) {
		$sorted_menu_items[ $menu_item->menu_order ] = $menu_item;
		$menu_items_tree[ $menu_item->ID ]           = $menu_item->menu_item_parent;
		if ( $menu_item->menu_item_parent ) {
			$menu_items_with_children[ $menu_item->menu_item_parent ] = 1;
		}
	}

	// Calculate the depth of each menu item with children
	foreach ( $menu_items_with_children as $menu_item_key => &$menu_item_depth ) {
		$menu_item_parent = $menu_items_tree[ $menu_item_key ];
		while ( $menu_item_parent ) {
			$menu_item_depth  = $menu_item_depth + 1;
			$menu_item_parent = $menu_items_tree[ $menu_item_parent ];
		}
	}
