username, password field with hidden submit button expecting to login on
enter key using forms implicit submission will work on FF & Opera but may
not work on IE & Safari.

> Second to your opinion, on the last line of the specs paragraph it says -
"If the form has no submit button, then the implicit submission mechanism
must just submit the form element from the form element itself."
