I am unsure if kernel is involved at all. It may be device firmware 
(have you checked for firmware updates?), it may be libinput as the 
device driver. Perhaps libinput may send some commands to touchpad to 
suppress generation of events for some interval of time.

Hypotheses:
- Issues are inherent to this model, so Windows users should suffer as well,
- Hardware issues with particular device.

If a dedicated discussion group exists then participants may be more 
experienced in debugging.

You posted output of xinput and mentioned evtest. I have never used 
"libinput debug-events", however I would try if this tool may provide 
more details.

I am unsure if you have read relevant parts of libinput docs
https://wayland.freedesktop.org/libinput/doc/latest/palm-detection.html

I hope I solved my variant of "buttons does not work for some period of 
time" by dropping a snippet into xorg.conf.d that enables tap-to-click. 
For me it is more convenient than clicks in the bottom area. My 
observation is that hardware click works more reliable if I raise the 
finger for a moment after moving cursor. However in my case period of 
clickbuttons inactivity is usually just a few seconds (unless prolonged 
by repeating clicks). Sometimes clicks are ignored when a finger is at 
the bottom touchpad edge.
