Android Appbarlayout с проблемой большой высоты текста

Appbarlayout имеет TextView может содержать большое количество текста.

В начале TextView - это 2 строки, и все в порядке, но когда я расширяю TextView, Appbarlayout обрезается, а когда я прокручиваю вверх, остальное пусто.

Обычный:

Расширенный:

Прокрутка вверх:

                } else {
                    text.setMaxLines(Integer.MAX_VALUE);
                    isOpen = true;
                }
            }
        });
    }
}

Это ошибка AppbarLayout или CoordinatorLayout?
