Problems with cut texts on resizing

[tsujan]

When the window is resized such that the old texts (= those before the last prompt) are cut, they can't be selected correctly, and so, they or their URLs can't be copied/opened correctly.

This is a result of lxqt/qterminal#76

This isn't the same as lxqt/qterminal#76. Here, the problem is about copying (URLs) and opening URLs, and there may be a way of doing it without implementing what is called "text reflow" in that report — I don't think "text reflow" is a good idea, BTW.
