I probably discovered why this happens.
The WM_DELETE_WINDOW command is being received with success, I tested
it.
The issue is that the command xmonad uses to spawn st double-forks the
process, making the SIGHUP signal not being sent to the correct pid. See
[1].
So the question remains if we should cover this case or not, since
xmonad's approach is probably nonsense. I never experienced this with
other applications though.
