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.

I've run into this issue as well. I find it a little hard to repro on the APG site since the menus collapse when the checked state changes, so here's a simpler repro: https://jsfiddle.net/o3uawj85/2/

The checked state change is read when it changes from unchecked to checked, but not when it changes from checked to unchecked. The other issue is that an unchecked menuitemcheckbox is read as if it were a menuitem -- no indication that it is checkable, or that it is currently unchecked.

I also still hear the "1" mentioned in the initial report.
