Copy command leaves a lot of zombie processes

[non-descriptive]

Basic information
Debug log: zellij-22.log

zellij --version: zellij 0.41.2

stty size: 33 140

uname -av:
Linux user 6.1.0-31-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.128-1 (2025-02-07) x86_64 GNU/Linux

Reproduction steps

1. Run zellij session using config with copy_command set and copy_on_select enabled
2. Select some text to make it into clipboard
3. Paste it somewhere to make sure it works
4. Copy again couple times
5. run command ps ax|grep wl-copy and see something like

 581867 ?        Z      0:00 [wl-copy] <defunct>
 614145 ?        Z      0:00 [wl-copy] <defunct>
 649179 ?        S      0:00 wl-copy

where is a zombie.

Issue description

On every copy on select new child process with copy command is spawned and previous command process (if any) turns into zombie process. My current copy command is wl-copy, but had similar issues with xclip, so likely it has issues with other copy commands.

I am also having this same issue. I tried with both xclip and xsel and both appear to leave zombie processes
