AFAIK, the CryptoManiac/Ed25519 is not affected

[CryptoManiac]

I believe there is a mistake. The referenced function has nothing to do with the message signing code. Neither the publicly available message signing method Ed25519.Sign nor its internal twin are expecting the public key among their arguments.

P.S. I find myself confused by the fact that the people are ignoring the documentation even when it comes to cryptography. 🫤
