configMapGenerator doesn't create the correct suffix when metadata.namespace: is set.

[shlomodaari]

What happened?

When the namespace is set in the deployment the kustomize doesn't add the suffix to the configMap

What did you expect to happen?

adding the suffix correctly

How can we reproduce it (as minimally and precisely as possible)?

# kustomization.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- resources.yaml

# resources.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: test-object
data:
  placeholder: data

Expected output

      - configMap:
          name: spinnaker-hb4d76k25c
      - configMap:
          name: orca-c88mftkf6c

Actual output

      - configMap:
          name: spinnaker
      - configMap:
          name: orca

Kustomize version

5.4.3

Operating system

workaround is to set the namespace on the kustomize instead the deployment
