I also only learned this quite recently and was surprised by this, but
yes, that is unfortunately how it works on X11. Pasting basically asks
the application that "copied" it to get the content. If that app is gone
in the meantime, there's nothing to paste anymore.

This will likely change with Wayland, but then it will also need some
unified API, which there is not yet, afaik.
