Background:

• I have a personal Microsoft account
• I have a work Microsoft account
• My work Microsoft account is a guest user in another tenant

Passkeys have been activated on the tenant of my work account, but I am not able to add one using Proton Pass.

Expected behaviour: I work through the set up passkey remedies, Proton Pass detects that I have multiple logins saved for https://login.microsoftonline.com/ and lets me select the login I want to attach to the passkey.

Actual behaviour: When I try to set up a passkey for my work account, Proton Pass has preselected my Microsoft personal account to save the passkey and I am not able to select another account.
