Indeed, there is an unconditional call to `forward-line', which makes it
impossible to for python-shell-send-defun to send the first line of the
buffer:

(defun python-shell-send-defun (&optional arg msg)
  [...]
    (python-shell-send-region
     (progn
       (end-of-line 1)
       (while (and (or (python-nav-beginning-of-defun)
                       (beginning-of-line 1))
                   (> (current-indentation) 0)))
       (when (not arg)
         (while (and (forward-line -1)
                     (looking-at (python-rx decorator))))
         (forward-line 1)) ; <-----------------------------------
       (point-marker))
      [...]
