Orphaned zsh processes from interactive shells executing commands
I noticed that when using powerlevel10k, commands run by tools forcing an interactive shell leave orphaned zsh processes owned by launchd. In this case they're doing this to get the interactive environment for the user, I believe IntelliJ and VSCode do something similar:

I can reproduce if I run commands interactively:
❯ zsh -ic 'echo hi'
hi
❯ ps -ef | grep echo
501 82079 1 0 11:54am ttys001 0:00.00 zsh -ic echo hi
501 82081 1 0 11:54am ttys001 0:00.00 zsh -ic echo hi
One of the processes exits soon after, but the other stays running indefinitely:
501 82079 1 0 11:54am ttys001 0:00.00 zsh -ic echo hi
I bisected my .zshrc and confirmed that disabling powerlevel10k avoids the problem. That's as much as I've been able to discover I'm afraid, it's not obvious to me which of the spawned shells this is:

Can you reproduce this with the following command?

emulate -L zsh -o err_return -o xtrace
if [[ -e ~/powerlevel10k ]]; then
command git -C ~/powerlevel10k pull
else
command git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k

command rm -rf ~/z
command mkdir -p ~/z

command cat >~/z/.p10k.zsh <<\END

}
Yes, rarely. When I do this manually from my regular shell I can reproduce almost every time. It might be a complete coincidence, but it seems to help if I start from scratch (i.e. remove z and powerlevel10k directories) before running the function:

Yes, when they hang up like this, it seems they do:
❯ ps -ef | grep -E 'echo hi$'
501 70025 1 0 7:25pm ttys004 0:00.00 zsh --no_globalrcs -ic echo hi

Thanks, let me know if there's anything else I can do to eliminate problems here. It's a real head scratcher.
What is the output of this command?
typeset -pm 'P9K_SSH|_P9K_SSH_TTY|TTY'
true &; ZDOTDIR=~/z zsh --no-globalrcs -ic 'echo hi'; true&
I am assuming you have ~/powerlevel10k and ~/z left over from the previous command.
❯ typeset -pm 'P9K_SSH|_P9K_SSH_TTY|TTY'
true &; ZDOTDIR=~/z zsh --no-globalrcs -ic 'echo hi'; true&
typeset TTY=/dev/ttys004
export _P9K_SSH_TTY=/dev/ttys004
export -i P9K_SSH=0
