 Hi @rcreators
 I tested PR 6150 using Chrome on macOS, and the update breaks the menu.
 ----

 When I navigate to the menu using the tab key, the visible focus is on the
 first parent menu item, and the submenu shows.
 Pressing tab again, I am expecting to be able to use the submenu, but the
 submenu is no longer visible, and I can't see where the focus is.

 ----

 I can only the escape key once to close a submenu.
 When I navigate to the menu using the tab key, the visible focus is on the
 first parent menu item, and the submenu shows.
 When I press escape, the submenu no longer shows.
 if I tab forwards from there, the visible focus os on parent menu item
 two, and its submenu shows.
 When I press escape, nothing happens.

 ----

 If I navigate with they keyboard past the menu and navigate backwards with
 Shift + Tab, focus moves to the wrong element. It moves to the parent menu
 item, not the the last item in the submenu.
