Regression in Buoyant Linkerd 2.19.5

We recently upgraded from version 2.19.4 to 2.19.5. On the surface it seemed to work fine. But we now get reports about issues with ExternalName services.
We have a couple of ExternalName services that map to another service in k8s. After the upgrade to 2.19.5 there are connection issues from applications that use the ExternalName service.
