Как получить одинаковый вертикальный размер TitledPanes в Gridpane? (JavaFX, конструктор сцен)

у меня проблема с вертикальным размером правого TiteldPane (см. рисунок ниже). Оба TitledPane помещаются в GridPane. Я хочу, чтобы меньший получил ту же высоту, что и левый. Я попытался установить Vgrow на «всегда» правой TitledPane, но ничего не произошло. Также я безуспешно пытался что-то сделать с регионом. Возможно ли это без указания им абсолютной высоты?

Заранее благодарны за Вашу помощь.
