Touchpad setting menu
SUMMARY
Selection of two-finger tap is not active despite there is support for this
from the touchpad itself. So it is inpossible to configure behavior or right
click or middle click on double tap through plasma settings.
This was working properly on 5.24 Plasma
STEPS TO REPRODUCE
1. Go to Hardware -> Input Devices -> Touchpad
2. Tapping and Two-finger tap are inactive and can't be selected
When installing xserver-xorg-input-synaptics "Tapping" menu becomes active, but
not Two-finger tap.
At the same time touchpad is reflecting on double-tap as right click. It is
also possible to change the behaviour of touchpad through "xinput set-prop 16
"libinput Tapping Button Mapping Enabled" 0, 1" - and it will switch to middle
click. But setting will remain inactive in UI.
EXPECTED RESULT
There is a way to change configuration with system settings.
