ignoreDifferences not working properly

[nebula-it]

Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

Setting the below ignoreDifferences does not show the diff, but still marks the item as out of sync.

  ignoreDifferences:
    - group: "*"
      kind: Secret
      name: cilium-ca
      jsonPointers:
      - /data/ca.crt
      - /data/ca.key

Here is how it looks in UI:

and if ignoreDifferences is not defined at all, then the diff is showing like:

To Reproduce

Deploy this application:

---
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: cilium
  finalizers:
    - resources-finalizer.argocd.argoproj.io
  annotations:
    argocd.argoproj.io/compare-options: ServerSideDiff=true
spec:
  destination:
    namespace: kube-system
    server: "https://kubernetes.default.svc"
  project: default
  source:
    chart: cilium
    repoURL: https://helm.cilium.io/
    targetRevision: '1.18.1'
  syncPolicy:
    syncOptions:
      - CreateNamespace=true
      - RespectIgnoreDifferences=true
  # https://docs.cilium.io/en/stable/configuration/argocd-issues/#solution
  ignoreDifferences:
    - group: "*"
      kind: Secret
      name: cilium-ca
      jsonPointers:
      - /data/ca.crt
      - /data/ca.key

Expected behavior

The UI should not show Out of Sync for items that are listed in ignoreDifferences
