running quit() doesn't reset the terminal

First: is this a bug report? A suggestion? Or asking for help?

A bug report I think, or maybe asking for help :)

# Problem description
I have a quit button in a ripasso, and in the new user wizard there is a quit button that I have implemented like this:

```
.button(super::CATALOG.gettext("Cancel"), |s| {
s.quit();
std::process::exit(0);
})
```

This doesn't reset the terminal for the user and it looks like this:


If possible code, or pseudo-code to reproduce the problem / present an idea.

See above.
