Control: retitle -1 With HandlePowerKeyLongPress=shutdown configured, a short 
press is interpreted as long press

When I created /etc/systemd/logind.conf.d/custom.conf with

If this is the whole content of /etc/systemd/logind.conf.d/custom.conf,
you are missing a [Login] section at the top of the file

It was the whole contents.
Adding the "[Login]" header (back) made it work \o/

I initially had that header, but in my attempts to get it to work, I removed
it again. I must have done something else wrong in my earlier attempts
which made it not work then, but I won't be able to recall exactly what.

It looks like there actually is a bug and not (just) a PEBKAC issue.
What I (actually) started out with, was the following custom config:
```
[Login]
HandlePowerKey=suspend
HandlePowerKeyLongPress=poweroff
```

And when I then pressed the power key *short*, it powered off the system.
My initial conclusion that logind.conf.d/custom.conf didn't work was incorrect.

If I remove or disable (via prepending it with '#') the LongPress action, then
it sees it as a short key press and does the desired thing: suspend.
If I set the LongPress action to 'ignore', then it also registers a short key
press as a short press and does the desired thing: suspend.
But if I set the LongPress action to 'shutdown', then it registers a short key
press as a *long* press and does the poweroff action.

Attached you'll find the custom config I used (same as quoted above) and
also the output from journalctl where all my physical key presses were short.

The journald output shows long and short key presses (with logind reacting accordingly) That looks all as expected and I don't understand the problem this is supposed to show.
