Steps to reproduce:
Go to a website in which you have a password saved.
Go to the login form and click on your username on the autofill window.
Then, even though you have already clicked once and filled the credentials, the autofill window still shows up repeateadly on the password field.
The autofill window should close when the password is filled.
