How to open files in the correct Sublime Text window instead of the most-recently-used Sublime Text window

sublime_text.sh

#!/bin/bash

# Do not -o pipefail because xdotool returns exit code 1 if no match
set -eu
# For debugging:
# set -o verbose

# When called from the command line, Sublime Text opens files in the most-recently-used window,
# and provides no option for controlling this behavior.  Work around this by searching for the
# window we *don't* want the file opened in, finding the other sublime_text window, then raising
# ("activating") it before opening the file.
UNWANTED_WID=$(xdotool search --all --desktop 0 --class --name '^(sublime_text|~/wiki/scratchpad\.md .*- Sublime Text)$' | head -n 1)
if [[ ! -z "${UNWANTED_WID:=}" ]]; then
	WANTED_WID=$(xdotool search --all --desktop 0 --class '^sublime_text$' | fgrep -v "$UNWANTED_WID" | head -n 1)
	xdotool windowactivate "$WANTED_WID"
	# Wait for window to actually activate before opening the file
	sleep 0.06
