I created a CR "parent" that creates a CR "child". The "child" CR has two ownerrefs: "parent" and "uncle" (another CR). The "parent" ownerRef blockOwnerDeletion is true; the "uncle" ownerRef blockOwnerDeletion is unset.

When I delete "parent", "child" is not deleted. We do not seem to honor blockOwnerDeletion on "child" being deleted, though we do remove the ownerRef. If I first remove the "uncle" ownerRef, "child" is deleted when I delete "parent".

Is this expected behaviour? It seems contrary to all docs I have found (and the field name!)

I would expect: that either child would be deleted, or that the parent deletion would hang (if the second ownerRef was considered blocking) until "child" has been deleted.
