[aria-required-parent] invalid false positive

Expectation: HTML here passes just fine

Actual: does not pass .toHaveNoVioliations through jest-axe:

Motivation:

HTML spec says:

Authors MUST ensure that menu item radios are owned by an element with role group, menu, or menubar in order to identify that they are related widgets. Authors MAY separate menu items into sets by use of a separator or an element with an equivalent role from the native markup language. If a menu or menubar contains more than one group of menuitemradio elements, or if the menu contains one group and other, unrelated menu items, authors SHOULD nest each set of related menuitemradio elements in an element using the group role, and authors SHOULD delimit the group from other menu items with an element using the separator role.

given html matches the 2nd case:

• menu contains more than one group of menuitemradio elements
• (…) other, unrelated menu items, authors SHOULD nest each set of related menuitemradio elements in an element using the group role
• (…) and authors SHOULD delimit the group from other menu items with an element using the separator role

• div role menu
  • div role group
    • button role menuitemradio
    • button role menuitemradio
    • hr, implicit role separator (making it explicit doesnt change anything fwiw)
    • a role menuitem

• minimum reproduction
• validates fine here as valid html, not sure if that checks for aria beyond redundancy though
• it worked fine before v4.0, so I presume something in this commit here broke
• removing div role group fixes it. adding a second group around the solo menuitem anchor on bottom also highlights this one as broken

That’s it. Adding 'group' to the array is the entire pr.

Yep, seems our standard object is missing group from required context of menuitemradio
