Libvirt allow hook to fork

If I have following Libvirt hook in /etc/libvirt/hooks/qemu.d/hook.sh

#!/usr/bin/env bash

if [[ $1 == "SEARCH_FOR_ME" ]]; then
    while true; do
        sleep 1
    done
fi

bash /etc/libvirt/hooks/qemu.d/hook.sh SEARCH_FOR_ME &
disown $!

touch /tmp/test123

exit 0

Now when I start any of my VMs this hook gets called and what I expected to happen is that a new process will be spawned and will run alongside VM. What actually happens is that libvirt for some reason knows that forked process is still running. Note that /tmp/test123 is being created. It seems that original bash script is being suspended.

2438 root        20   0     0     0     0 Z   0.0  0.0  0:00.00 bash
 2439 root        20   0  4396  3200  2944 S   0.0  0.0  0:00.04 bash /etc/libvirt/hooks/qemu.d/hook.sh SEARCH_FOR_ME

Also while running the same hook in my terminal I can't observe the same behavior. nohup works the same way and doesn't fix this issue. My system:

Artix Linux (OpenRC 0.53)
Hyprland WM (Wayland)
Libvirtd + Virt Manager
