When using Wayland, Screen Energy Saving doesn't work.

Either waiting for the switch off timer, or using Ctrl + Alt + D the outcome is
the same:

1. display turns off
2. display says that there is no signal/input
3. display turns off again
4. display wakes up immediately

Journal gives the following:
plasmashell[2276] qt.qpa.wayland: Wayland does not support
QWindow::requestActivate()

At bugs.kde.org there is the bug number 462695
(https://bugs.kde.org/show_bug.cgi?id=462695) where it claims the bug was
resolved at KDE side and the fix has to be provided by openSUSE.

My specs:
openSUSE Tumbleweed
Kernel 6.4.11-1-default
DE Plasma 5.27.7
CPU Intel i5-4670K
GPU AMD ATI Radeon RX 6750 XT

Note: Everything works has expected using X11.
