VoiceOver on menuitemcheckbox role

A link to replicate the issue: https://www.w3.org/TR/wai-aria-practices-1.1/examples/menubar/menubar-2/menubar-2.html. Notice two issues exists.

   The Bold / Italic menu items under Style/Color column has menuitemcheckbox role, the Voice Over in MacOS will incorrectly read it as '1 Bold checked menuitem' when the menu item is selected. 
  
   Another issue I notice is when select / deselect menu item with menuitemcheckbox role, its 'aria-checked' property will change based on the selection, but voice over ignores this 'aria-checked' status change.
