Why does Neovim behave differently from Geany when launched with nohup and &?

When I open Geany I need to launch it with nohup , e.g. nohup geany test.txt & so that when I close my shell, from which I launched it Geany does not get closed. I noticed that this is not the case with Neovim , simply xdg-open test.txt is enough (provided that I had run xdg-mime default nvim.desktop text beforehand). Executing nvim test.txt & or nohup nvim test.txt & results in the process being launched but without the editors window even being visible. **1.** In the situation described above, why go **Geany** and **Neovim** behave differently? **2.** In the environment where I have access to nvim binary but have not done yet (or cannot run) something like xdg-mime default nvim.desktop text or mimeopen -d .txt, how might I launch nvim in a new window so that it does not get closed when I close the shell from which I launched it? P.S. I use Bash.
