In the past, Safari on MAC entirely ignored the server-asserted contents of
certificate_authorities in the TLS CertificateRequest handshake message,
and would offer *all* possible client certs to the user.  Has this
bug been fixed in Safari?  I remember customer messages where clients
were refused that were erroneously sending AppleID client certs...
