Fidelity obfuscated username issue

Fidelity (https://www.fidelity.com) cleverly obfuscates the login username by replacing the trailing characters with asterisks. So, for example, if your login is “123456789”, the web UI obfuscates it to “******789”.

1Password sees the obfuscated version and offers to save it. In subsequent login attempts, 1Password fills the Username field with the obfuscated text.

This issue isn’t new. It’s longstanding. I just hit it again, though, and figured I’d report it in case there’s something you can do about it. 

Thanks.
