HostAliases not shown in argocd diff nor sync without replace

[aroundthecode]

Describe the bug

• I've a manifest where I set a HostAliases section in my deployment then removed it.
• Manifest is corectly generated
• I can see HostAlias section filled in in "live manifest"
• HostAlias is set as an empty array in "desired manifest"

• No difference is shown in diff panel
• Project is not OutOfSync but stay In Sync
• No modification occurs if I run normal sync
• HostAlias is correctly set to empty array if i run a sync with "Replace" option flagged

If any additional differences are present, only such differences are snown, not hostAlias ones

I've checked argocd-cm configmap for ignoredifferences but it only contains sections I configured:

resource.customizations: |+
    networking.k8s.io/Ingress:
      health.lua: |
        hs = {}
        hs.status = "Healthy"
        return hs
  resource.customizations.ignoreDifferences.Secret: |+
    jqPathExpressions:
    - '.data."liquibase.tar.gz"'
    - '.data."kafka.tar.gz"'
  resource.customizations.ignoreDifferences.all: |+
    jqPathExpressions:
    - '.metadata.labels."helm.sh/chart"'
  resource.customizations.ignoreDifferences.external-secrets.io_ExternalSecret: |+
    jqPathExpressions:
    - '.spec.data[].remoteRef.conversionStrategy'
    - '.spec.data[].remoteRef.decodingStrategy'
    - '.spec.data[].remoteRef.metadataPolicy'

• create a deployment with Hostalias
• set Hostalias to []
