Product:VoiceOver Product Version:macOS 10.15.5
Classification: Reproducible:
1. With VoiceOver running, open either Safari or Chrome
2. Go to https://w3c.github.io/aria-practices/examples/menubar/menubar-editor.html
3. Open the Style/Color menu in the Example menubar
4. Arrow down to the Italic menu item and type Space or Enter to check it
5. Arrow down to the Black menu item (this is a menuitemradio)
   VoiceOver says "1, Black, checked, menu item"
6. Arrow back up to Italic (this is a menuitemcheckbox)
   VoiceOver says "1, Italic, checked, menu item"

The "1" at the beginning of the menu item's name is unexpected and unnecessary.
