Is there a way to generate a metamask signature without it looking like a card blanche on Metamask?

FWIW - I am linking an issue in a separate library where the sign personal message works correctly, in case it helps with fixing it here:

I have a feeling it has to do with the way you are encoding the message. Metamask isn't recognising it as a personal message (with the appended text that prevents it from being used as a transaction).
