Test still fails for Hostname.
kubectl get listener/listener-nginx-long-name-approaching-k8s-limits-0 -o jsonpath='http://{.status.ingressAddresses[0].address}:{.status.ingressAddresses[0].ports.http}/pod-name'
trys e.g.
curl -s http://worker-wfcawizc:32396/pod-name
but fails with e.g.

curl http://worker-i7sss39m:30283/pod-name
curl: (6) Could not resolve host: worker-i7sss39m

On kind we have e.g.:

curl -s http://stackable-data-platform-control-plane:31008/pod-name
nginx-long-name-approaching-k8s-limits-0

Test case for Hostname will be omitted on OKD as it not clear if this is a limitation in OKD.
Kind: (the test runs but the curl commands are deactivated)
