`network/ipGroups`: delete ipGroups failed with `IpGroupsHasFirewallPolicyReferences` even the firewall policy has already deleted

[wuxu92]

I want to delete the ipGroups just after deleting the firewall policy, the DELETE api response error as below. I'm sure the firewall policy that referenced to the ipGroupgs has been deleted successfully(DELETE API with status 200).

{
    "error": {
        "code": "IpGroupsHasFirewallPolicyReferences",
        "message": "IpGroups '/subscriptions/xxxx/resourceGroups/acctestRG-networkfw-230911125634169038/providers/Microsoft.Network/ipGroups/acctestIpGroupForFirewallNetworkRulesSource' cannot be deleted since there are firewall policies using this resource."
    },
    "status": "Failed"
}
