Как включить JavaScript-функцию window.open () в браузере PyQt5 Python

Question

Я занимаюсь разработкой веб-браузера на Python и PyQt5.Браузер работает нормально, но новая вкладка и javascript window.open () не работают.Я хочу знать, как включить новые вкладки и всплывающие функции.Функция javascript alert () работает, но новое окно и новая вкладка не работают.

Если вы мне поможете, я буду вам очень благодарен.
