🐛 Cache: Keep selectors when byObject.Namespaces is defaulted #2747
Conversation

Prior to this patch, configuring for example a labelSelector in `ByObject` and then inheriting namespaces from `DefaultNamespaces` meant that the `labelSelector` would be ignored. This is because if namespaces are configured, we set p a multinamespace cache. If we do that, we expect each namespace entry to have the appropriate selectors configured. Unfortunately we defaulted the configs for`byObject.Namespaces` before defaulting `byObject.Namespace` itself, causing the above-described issue. This change also adds a couple more tests for the cache defaulting.
