MenuBar: Keyboard navigation

Describe the bug

Describe the bug
I've updated Primereact to the latest version (10.9.4) and noticed that keyboard navigation doesn't work anymore for the Menubar. Adding an onKeydown event handler to the menuitem with pass through options will solve the issue just partially. While this work for the 0 level menu items it still doesn't work for the submenu items. I've also noticed that onKeydown handler isn't being passed to the nested items.

Additional info
I was using both: custom templates and without any template for the menuItem.

System Information

primereact 10.9.4

Steps to reproduce the behavior

1. Open stackblitz.
2. Press tab to focus the first element.
3. Notice that the element isn't being focused.

Expected behavior

Pressing tab should focus the first element and the further navigation with arrows should be enabled.

Start with the linked StackBlitz reproducer and trace the Menubar keyboard handling for both top-level and nested menu items, including cases with and without custom templates. Check how the keydown handler reaches nested items. Done means Tab focuses the first item and arrow-key navigation works throughout the menu.
