Certain Passkeys only ask for Apple Passwords

I've saved my Passkey for Google in 1P, but when I go to Google to log in, I get a popup on Safari saying to go to the Apple Passwords app. I've disabled Passwords app in Safari settings (now the tab is entirely gone).

In System Settings, AutoFill and Passkeys, I've turned off Autofill. The only thing left is "Set up codes in" and there's a dropdown that ONLY includes the Passwords app.

1P is enabled in Safari. In 1P for Safari Settings --> General, the toggle is ON to make 1P the default password manager in this browser.

And yet, when I go to accounts.google.com, and it says it's going to use a passkey, I get a popup from Apple Passwords telling me to use it to manage my passkeys. My only options are Open "autofill & passwords", or other sign in options. That option makes me use my phone to scan a QR code. At this point this is WAY harder than not using a passkey.

Any idea how I get Apple Passwords to get out of my way so I can use 1P to use my passkeys?
