Can you clarify what you mean about not detecting? Do you mean not
detected as clickpad?
Your extended capabilities 0x0c show bit 0x100000 set which current
kernel uses as part of clickpad detection. Also, if Yan's patch is of
use to you, then that means kernel is only reporting BTN_LEFT which
also indicates its detected as clickpad by kernel.

Make sure palm detection is off or at least palm width value is higher
than value of EmulateTwoFingerMinW as they compete with each other.
EmulateTwoFingerMinW is the extremely important property for the types
of jumps your describing here. If you can't get that working then
jumps will occur.
Can you confirm which version of xf86-input-synaptics your testing
with? It must be at least 1.3.0 or newer for EmulateTwoFingerMinW to
be be useful for these type jumps.

If you continue to have issues, I would appreciate if you can use
"evtest" tool and record events to log file while your performing
sequences that cause jumps and send logs directly to me. From those I
can verify if its a configuration issue of xf86-input-synaptics or
something that just hasn't been accounted for yet in
