systemd timers - WakeSystem doesn't work with systemctl --user

Hello. I have a script that is launched by a timer which also wakes up the system (in case it's suspended) on a OnCalendar event.
I enable and start the timer with:

systemctl --user start backup.timer
systemctl --user enable backup.timer

It worked on my previous slightly non-updated arch installtion. Now that I've reinstalled and updated it, it doesn't work anymore and I get the following errors:

...
systemd[1316]: backup.timer: Failed to enter waiting state: Operation not permitted
systemd[1316]: Failed to start run backup.
...

If I remove WakeSystem=true from my .timer file everything works as before, so my questions are:

• does the user need special permissions to wake up the system?

• If so, how to give them?

• Is it a bug (since it worked before) or am I forgetting something?

Joelmo on GitHub seems to have the same issues (Feb 14, 2017), which he solved by disabling the WakeSystem functionality altogether.

Sounds like a flaw in systemd...I mean, if you can systemctl suspend as a user

Yes,

$ systemctl suspend 

works if launched by the unpriviledged user
