Can't use security keys (u2f/webauthn) with oauth2 IMAP authentication
When attempting to configure a gmail (or G Suite) account with a security key as a second factor of auth (i.e. a YubiKey providing U2F or WebAuthn), the authentication webpage reports that the browser doesn't support them. A workaround for some domains is to use TOTP instead but this isn't always feasible.
Confirmed on 3.44.4 (Fedora 36) for multiple domains (Google, Okta). Not sure if this should be closed in favor of an upstream bug, or if it's worth considering other options (e.g. allowing the authentication pages to be opened in the system browser instead).
