Fwd: WCAG application menu bug report

Hey! 

<li role="menuitem" aria-haspopup="true" tabindex="-1" aria-expanded="false">
that's not fair! You the specification says no to aria-expanded to be applied on the menuitem, whereas you use it!
that's just not fair.

Good day Sirs!
i found a   bug   here: https:// www.w3.org/WAI/tutorials/menus/examples/appmenu/
the   bug    is:
if you  click  the expandable    menubar   >    menu   >    menuitem    physically by mouse, then    LEFT   /    RIGHT   arrow keys navigation  terminates...
The    UX   is alright, i can propose something much better! 
Don't beieve? Get in touch.
With respect, Zabludovskiy Grigoriy.
