Syncing an Application with RespectIgnoreDifferences empties everything inside the ignore within the Applicationset

[DJGizmof]

We have an Application with an ignoreDifferences:

apiVersion: argoproj.io/v1alpha1
kind: Application
...
spec:
  ignoreDifferences:
      - group: argoproj.io
        jsonPointers:
          - /spec/generators
        kind: ApplicationSet
        name: appset-name
...

We also have an applicationSet holding the data:

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
spec:
  generators:
    - list:
        elements:
          - branch: a-branch
            sanitized_branch: a_branch
          - branch: another-branch
            sanitized_branch: another-branch

When the sync on the application is run, we end up with the following data inside the ApplicationSet:

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
spec:
  generators:
    - list: {}

In previous version(s) of ArgoCD we ended up with the same data as before the sync.
The expected behavior would be that the whole generator-list remains untouched.

We experienced this bug with Argocd Version:
