What steps will reproduce the problem?
(1) Go to https://www.justfab.com/, click Sign-in
(2) Save some credentials on that login form
(3) Visit https://www.justfab.com/ again, click Sign-in

What is the expected result?
Credentials being autofilled

What happens instead?
No automatic filling. Filling on demand works fine.

Both the new and the old parser return no username found. However, somehow the new code for filling in PasswordautofillAgent exits PasswordAutofillAgent::FillUserNameAndPassword and refuses to fill, while the old renderer code ends up having filled.
