This is definitely a regression but I am not sure when it broke.
Previously, if I have multiple logins for the same page (testing our app), I was able to type in the username field and the suggestions would only display matching items.
With the recent releases, all the items are displayed when I start typing the username.
I expect the account/password suggestions to filter based on what I am typing in the username field.
