Rename PasswordForm::is_zero_click to PasswordForm::skip_next_zero_click.
In addition to that the patch restores the unique key in the LoginDatabase which was incorrectly abolished in https://codereview.chromium.org/
818443004. The former key was (origin, signon_realm, username_element, username_value password_element, submit_element). The correct one used by Sync is without submit_element.
