Deleting VMAgent CR with statefulMode enabled doesn't delete the StatefulSet

[blesswinsamuel]

Operator Version: Tried with both 0.25.1 and 0.26.3. Observed the same issue on both versions.

Minimal example:

apiVersion: operator.victoriametrics.com/v1beta1
kind: VMAgent
metadata:
  name: test-vmagent
  namespace: testing
spec:
  externalLabels:
    cluster: kind-cluster
  image:
    pullPolicy: IfNotPresent
    repository: victoriametrics/vmagent
    tag: v1.79.0
  remoteWrite:
  - url: http://test-vminsert:8480/insert/0/prometheus
  statefulMode: true
  statefulStorage:
    volumeClaimTemplate:
      spec:
        resources:
          requests:
            storage: 2Gi

Once the statefulset is up, delete vmagent:

$ kubectl delete vmagent -n testing test-vmagent
vmagent.operator.victoriametrics.com "test-vmagent" deleted

Observed logs on victoriametrics operator:

01:10:45.000  INFO Reconciling logger="controllers.VMAgent" vmagent="testing/test-vmagent"
01:10:45.000  INFO Reconciling logger="controllers.VMAgent" vmagent="testing/test-vmagent"

01:10:45.000  INFO Reconciling logger="controllers.VMAgent" vmagent="testing/test-vmagent"

Observed that statefulset is not deleted. Once the finalizer was removed, it got deleted.

$ kubectl get sts -n testing
NAME                   READY   AGE
vmagent-test-vmagent   1/1     9m46s
