//
// The Kube 1.20 garbage collector asserts some new behavior in regards to invalid owner
// references (i.e., when you have a namespace-scoped owner references for a cluster-scoped
// dependent, the cluster-scoped dependent is not removed). We also found a bug in the 1.20
// garbage collector where namespace-scoped dependents are not garbage collected if their owner
// had been used as an invalid owner reference before - this bug causes our test to fallover
// because we are setting a namespace-scoped owner ref on this APIService.
//
// We believe that the best way to get around this problem is to update our kubeclient code to
// never set owner references on cluster-scoped objects. After we do that, we will uncomment this
// part of the test.
