:wq! messes up the terminal

[Pistahh]

Summary

When I try to edit something I have no permissions for and try to save and exit with :wq!, it exits the editor but leaves the terminal in a messed up state:

for reference, this is how it should look like:

I use zsh and my prompt is set up by https://github.com/Pistahh/dot-zsh/blob/master/.zsh.d/prompt

Reproduction Steps

I tried this:

1. hx /etc/hosts as non-root (so no write permissions)
2. modified it
3. tried to save and exit with :wq!

I expected this to happen:

terminal is not messed up

Instead, this happened:

terminal is messed up

I think I've narrowed it down to needing to reset isig (stty isig) on exit.

I believe this was fixed with #4081
