SUMMARY
After update to plasma 6.3 wacom tablet stopped working in wayland apps that ignores tablets by default, like Vesktop (electron based), MPV player. Before that KDE used some workaround that sends fake mouse clicks into apps, and now it's don't. I tried searching the settings, but i can't find option to turn this workaround on.

STEPS TO REPRODUCE
1. Update to plasma 6.3, use wayland session.
2. Download MPV player or Vesktop, or any electron app
3. Try to navigate app using only wacom tablet.

OBSERVED RESULT
wacom tablet completely ignored

EXPECTED RESULT
Mouse-like behavior, like it was in plasma 6.2 and like it is on X11.

SOFTWARE/OS VERSIONS
Windows: no
macOS: no
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: yes
KDE Plasma Version: broke after 6.3 update, now on 6.3.3, still not fixed
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.2
