SUMMARY
I use a Huion H1161 pen tablet to navigate in the system integrally, but prefer X11 session. Normally, X11 causes many fewer problems.
The Wayland session does not register rightly the right-click emulation from pen or any button of my tablet. The context menu, just select and activate over the element in the center of screen.
This problem does not happen in an X11 session, at least until yesterday, when I've moved from KDE Neon to Debian. (Should I open a new report to that case?)

Debian Plasma session with X11, now conflict with Huion driver as soon as the session starts. The pen works well until Huion driver starts too, soon the pointer freezes position. Closing huiontabet driver with 'pkill' in the Konsole solves the problem parcially. Use the module (IDK how to call it) from Config System to setup pen tablets recognizes my tablet, but it is too basic: don't have options to set the buttons on the tablet, just on the pen. So, don't use the huiontablet driver is not an option.
  
STEPS TO REPRODUCE
1.  Start a Plasma session with Wayland
2. Right-click button any element on screen

OBSERVED RESULT
The context menu does not follow the pointer position on screen and is activated to the element in the center of screen.

EXPECTED RESULT
The context menu should be activated to the element under pointer position.
