Finally I make a solution for this problem.

                while True:
                driver.execute_script("document.getElementsByClassName(\'review-dialog-list\')[0].scrollTo(0, document.getElementsByClassName(\'review-dialog-list\')[0].scrollHeight)")
                sleep(5)
                new_height = driver.execute_script("return document.getElementsByClassName(\'review-dialog-list\')[0].scrollHeight")
                #print('new_height:', new_height)
                if new_height == last_height:
                    break
                else:
                    last_height = new_height
