It turns out that systemd is the culprit (if not in full then at least
it takes a part of the blame).
In recent versions of systemd, logind seems to be able to handle ACPI
events. By default this functionality is enabled, so lid close or
suspend key will trigger instant suspend via systemd-logind. My guess is
that xfce power manager is not aware of that (gnome's pm is), hence it
does not ignore the suspend event.

As a solution, in /etc/systemd/logind.conf put the following lines:
HandlePowerKey=ignore
HandleSuspendKey=ignore
HandleHibernateKey=ignore
HandleLidSwitch=ignore
