I'm looking at this image registry.redhat.io/openshift4/ose-etcd-rhel9:v4.14.0-202411190204.p0.g5ed5044.assembly.stream.el9 and it has a content manifest file /root/buildinfo/content_manifests/ose-etcd-container-v4.14.0-202411190204.p0.g5ed5044.assembly.stream.el9.json which has empty content_sets.

We use the content_sets which correspond to the highest metadata.image_layer_index to determine which redhat products an image belongs to. For that image this file has the highest image layer index value so our matching logic fails.

Is it expected that the content_sets are empty in this file? If so, should we just fall back to the next highest image layer index content sets?
