I tested this over and over. I think it's a 'nasty' bug here.

#!/bin/bash
(
  # sleep 1    # or whatever not very quick command!
  set -m;
  sleep 10 &   # or whatever command takes some time to complete
  set +m;
  pid=$!
  ( sleep 1; kill -- -$pid ) &
  wait $pid
)

without sleep 1 commented you get:

./bug.sh: line 8: kill: (-760) - No such process

with it uncommented it works as expected

./bug.sh: line 10:   492 Terminated              sleep 10
