Webview Bookmark

Question

Я пытаюсь добавить закладку в свой веб-браузер и добавил ее, но она сохраняет только одну ссылку.например, если я нахожусь на https://www.wikipedia.org/ и сохраняю эту закладку, и я просматриваю Википедию и попал по этой ссылке https://en.wikipedia.org/wiki/Portal:Featured_content, закладка покажет удаление в снэк-баре и просто сохраняет 1 ссылку и удаляет 1 ссылкуЯ хочу сохранить обе ссылки.
