Okay, narrowed it down:

(setq hook
      (lambda nil
        (remove-hook 'minibuffer-setup-hook hook)
        (setq-local overlay
                    (make-overlay (point) (point) nil
                                  'front-advance 'rear-advance))
        (setq-local truncate-lines t)
        (setq minibuf-after-string
"a\nbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb\nccc")
        ;; (setq minibuf-after-string "a\nbbbbbbb\nccc")
        (move-overlay overlay (point-max) (point-max))
        (overlay-put overlay
                     'after-string minibuf-after-string)))

(unwind-protect
    (progn
      (add-hook 'minibuffer-setup-hook hook t)
      (read-from-minibuffer ""))
  (remove-hook 'minibuffer-setup-hook hook))
