bash and fish close without warning, zsh does not.

[Palaress]

Describe the bug
zsh without any running for- or background tasks throws waring before closing by OS.

Environment / Versions

• kitty: kitty 0.42.1 created by Kovid Goyal
• Archlinux: Linux 6.15.4-arch2-1
• zsh: zsh 5.9 (x86_64-pc-linux-gnu)
• bash: GNU bash, version 5.2.37(1)-release (x86_64-pc-linux-gnu)
• fish: fish, version 4.0.2

Steps to reproduce the behavior

1. Install kitty, bash, fish and zsh
2. Start new kitty shell with fish like kitty --config NONE fish --no-config, or with bash like kitty --config NONE bash --norc --noprofile.
3. Close it by OS, x button on window, or $mod + q or however you close windows in your OS. This just closes the kitty window for me, without any warning.
4. Open new kitty window with zsh like kitty --config NONE zsh --no-rcs, and close it by OS again. Throws warning: "Are you sure you want to close this OS Window? It is running: zsh. [Yes] [No]"

Expected behavior

zsh should close without any warning just like bash and fish.

If you dont want confirmation when closing windows, use the option for
it:

Hi @kovidgoyal,
thanks for the quick reply.

I want it to work with confirm_os_window_close -1 which it does not with zsh.

As I understand -1 is the default value, that's why I was using --config NONE.

I am fine renaming the issue "confirm_os_window_close -1 ignored for zsh" though.

Adding shell_integration enabled to kitty-test.conf doesn't change behavior. In both cases bash and fish don't show any warning before closing.

it works out of the box with zsh, bash and fish. It depends ons hell
integration, make sure you havent disabled that. Run zsh using

kitty -o shell=zsh

rather than kitty zsh

I have stripped my previous zshrc and found the problematic part.

I have added precmd_functions=() to be able to change the precmd() function and so the title of the OS Window (wayland compositor).

Can you tell how zsh is recognized as a shell and what I could add in the precmd() to get it the functionality working again?
