SUMMARY
I use a pen tablet as my pain input device instead of a mouse. Various interfaces of KDE are not reacting to pen inputs and some of those have already been reported. I didn't see a report for this one yet.

The taskbar (usually the panel at the bottom) does not react to pen inputs (pressure and side buttons).
This is a big issues since it is so essential for daily use.

STEPS TO REPRODUCE
1. Use a pen tablet
2. Try tapping or using the pen buttons while having the cursor on the taskbar

OBSERVED RESULT
No reaction from the taskbar.

EXPECTED RESULT
Pen tapping and side buttons should always be interpreted as left, middle and right click.
