Objects not discovered as dependent, but parent-object discovered as dependency

Hey @tohjustin :wave: :) I think I've experienced a bug and hope this report helps improving your wonderful tool. Please let me know if you want more info or something else!

Story time

I've installed package-operator which brings its own CRDs which are strictly organized in a hierarchy.

After installation of the operator [1], there is a tree of objects, glued together by ownerReferences that looks like this:

ClusterPackage/package-operator
-> ClusterObjectDeployment/package-operator
  -> ClusterObjectSet/package-operator-$hash
    -> Actual kubernetes objects

But some object relations are missing from kubectl-lineage's output. This is the output for kubectl lineage clusterpackage package-operator:

I know that there is a missing ServiceAccount which I can reverse query for its dependencies with kubectl lineage -D -n package-operator-system ServiceAccount/package-operator:

and also a deployment kubectl lineage -D -n package-operator-system Deployment/package-operator-manager:

NAMESPACE                 NAME                                               READY   STATUS   AGE

I'll link the Package sources for reference [2]. The full list of missing dependent objects should be:

Deployment/package-operator-manager
ServiceAccount/package-operator

All objects have proper ownerReferences set up. I've tried to include all relevant object manifest in the attached dump. [3]
