PIV does not render subject OID 1.2.840.113549.1.9.1 key name

OS: Windows 11
Authenticator: 7.3.2
Yubikey 5 NFS f/w 5.4.3

I have cert in slot 9a that contains OID 1.2.840.113549.1.9.1 (pkcs-9-at-emailAddress) in the certificate subject.

The result of which is a value that renders like follows for the subject

CN=First Surname,1.2.840.113549.1.9.1=email@test.org,O=Name,L=Locale,C=XX

Or as followed when the subject is hovered over.

CN=First Surname,1.2.840.113549.1.9.1=email@test.org
O=Name
L=Locale
C=XX

Whilst the OID is deprecated, it is not out for removal. It would be useful for Authenticator could render the attribute name correctly, as either E or emailAddress

Alternatives are to use a SAN entry of type UPN for RFC 822 Name, but legacy applications cannot always used these.
