lfrun & quit-on-cd(from lf wiki) not working

[shubham-cpp]

I was trying to make the lfrun work with quit-on-cd which mentions a trick to cd to the current directory when quitting.
But for some reason its not working as expected.
If I run regular lf it exits and cds to expected directory but when I do lfrun it doesn't

Minimal ~/.config/lf/lfrc

set cleaner ~/.config/lf/cleaner
set previewer ~/.config/lf/preview
set shell bash
set shellopts '-eu'
set ifs "\n"

cmd quit-and-cd &{{
  pwd > $LF_CD_FILE
  notify-send "quit-and-cd" "$LF_CD_FILE\n$(cat $LF_CD_FILE)"
  lf -remote "send $id quit"
}}
map Q quit-and-cd

Modified ~/.local/bin/lfrun

#!/bin/bash
set -e

cleanup() {
	exec 3>&-
	command rm "$FIFO_UEBERZUG"
}

lf() {
# https://github.com/gokcehan/lf/wiki/Tips#cd-to-current-directory-on-quit
	export LF_CD_FILE=/var/tmp/.lfcd-$$
	command lf $@
	if [ -s "$LF_CD_FILE" ]; then
		local DIR="$(realpath "$(cat "$LF_CD_FILE")")"
		if [ "$DIR" != "$PWD" ]; then
			echo "cd to $DIR"
			cd "$DIR"
		fi
		command rm "$LF_CD_FILE"
	fi
	unset LF_CD_FILE
}

if [ -n "$SSH_CLIENT" ] || [ -n "$SSH_TTY" ]; then
	lf "$@"
else
	[ ! -d "$HOME/.cache/lf" ] && mkdir --parents "$HOME/.cache/lf"
	export FIFO_UEBERZUG="$HOME/.cache/lf/ueberzug-$$"
	mkfifo "$FIFO_UEBERZUG"
	ueberzug layer -s -p json <"$FIFO_UEBERZUG" &
	exec 3>"$FIFO_UEBERZUG"
	# trap cleanup HUP INT QUIT TERM PWR EXIT # Also tried this one
        trap cleanup HUP INT QUIT TERM PWR EXIT
	lf "$@" 3>&-
fi
