Why do we have an extra copy of this when it is inside
|proviionally_saved_form_| as well?

[dvadym, 2016/04/06 16:02:20]

|provisionally_saved_form_| is reset in the end of CreatePendingCredentials().

[vabr (Chromium), 2016/04/06 22:42:11]

Ah, fair enough. An alternative would be to copy it into |pending_credentials_|
inside CreatePendingCredentials. But If you feel that would be confusing, I'm
fine with the current status.
