istio: istioctl analyze: showing invalid error on release 1.13.2

Bug Description

On the same cluster when running same command istioctl analyze -A

When the istioctl version is 1.13.2 it is showing the following as a error in the result: Error [IST0101] (Gateway istio-system/istio-ingressgateway) Referenced selector not found: "istio=ingressgateway"

But when istioctl version is 1.12.2 it not showing anything as such.

Upon manual verification of the cluster the error looks to invalid. And all traffic are working fine in the cluster.

Upon verification of one of the gateway pod I can see the label:

$ kubectl describe pod istio-ingressgateway-abcd -n istio-system
Labels:       
              istio=ingressgateway

Also Istioctl validate does not seems to show any issues:

kubectl get gw istio-ingressgateway -n istio-system -o yaml | istioctl validate -f –
kubectl get deployments -o yaml -n istio-system | istioctl validate -f –
kubectl get services -o yaml -n istio-system | istioctl validate -f –
kubectl get pods -o yaml -n istio-system | istioctl validate -f –
