Useless IS NULL check on menu item load

-- HikaShop version -- : 6.6.0
-- Joomla version -- : 6.1.3
-- PHP version -- : 8.4

hikashopMenusClass filters all loaded menu items via "b.title IS NOT NULL" where "b" is as alias of "#__menu_types" table.

"#__menu_types.title" is not a nullable column, hence this clause makes no sense, and join to #__menu_types is also completely useless.

Sorry, posted to incorrect forum, please move to Bugs.
