If I have multiple logins for the same site and I use the extension to launch/open one of them, bitwarden should set the “last used login” for the site to the one I just selected. Hence, if I autofill the intended login will be used.
e.g., if I launch “Amazon (Billy)” via bitwarden, then autofill should fill Billy’s login, not Sally’s or Tommy’s.
This should also be tested with the experimental “autofill on page load”
