The "HAAC_List_Group_ListItem" might either miss the requirement or duplicate the "Rpt_Aria_RequiredParent_Native_Host_Sematics" rule #3796
It looks like, from the description, the purpose of the rule "HAAC_List_Group_ListItem" is to check group role applying to the list, but the actual implementation is a special case of more generic rule "Rpt_Aria_RequiredParent_Native_Host_Sematics".
Aria has a specific requirement when the group role applies to the listbox: "when a group is used in the context of a listbox, authors MUST limit its children to option elements.", but the implementation of the rule is not for the requirement.
suggest either removing the rule and adding a new rule for the requirement or changing the implementation logic and the help and message to fulfill the aria requirement.
