On this doc item: https://google-auth.readthedocs.io/en/latest/reference/google.auth.compute_engine.credentials.html#google.auth.compute_engine.credentials.Credentials.service_account_email The rendered docs say simply `The service account email.` However, the [docstring](https://google-auth.readthedocs.io/en/latest/_modules/google/auth/compute_engine/credentials.html#Credentials.refresh) has more information: ``` """The service account email. .. note: This is not guaranteed to be set until :meth`refresh` has been called. """ ``` Why is this important note not rendered?
