Parent list key is not validated if not provided via RESTCONF

In the ietf-netconf-acm module there is a list with an embedded list:

list rule-list {
    key name;

    leaf name {
        type string {
            length "1..max";
        }
    }

    list rule {
        key name;

        leaf name {
            type string {
                length "1..max";
            }
        }
    }
}

If you PUT /data/ietf-netconf-acm:nacm/rule-list/rule=test this rule, it will be accepted:

{
    "ietf-netconf-acm:rule": [
        {
            "name": "test",
            "module-name": "*",
            "access-operations": "*",
            "action": "deny"
        }
    ]
}

Every time you PUT that rule, a new rule-list is created with empty name that is a key and must be mandatory:

{
    "name": null,
    "rule": [
        {
            "name": "test",
            "module-name": "*",
            "access-operations": "*",
            "action": "deny"
        }
    ]
}
