libinput debug-events

i have installed libinput on a razer blade stealth which is running archlinux.
The "dwt" and "tap to click" are enabled as shown below.

        libinput Tapping Enabled (296): 1
        libinput Tapping Enabled Default (297): 0
        libinput Disable While Typing Enabled (307):    1
        libinput Disable While Typing Enabled Default (308):    1 

linux kernel: linux-lts 4.9.52-1
libinput: 1.8.3-1

Everything works well except the dwt is not really working (i could keep moving
the mouse pointer using the touchpad even if i keep pressing a key on the
keyboard). and so while i am typing, the cursor will move away as it looks like
a tap is detected accidentally.

At first i was thinking if it is the same issue with this bug 102649. But as
Peter mentioned, it should be more likely that the dwt didn't get paired with
the laptop keyboard as there are two internal keyboards with exactly the same
identifiers exist in the razer laptop bug 102039, comment 16.

>From the attached output log, of my laptop it seems that the dwt didn't get
activated with the keyboard. and event 5 & 9 are the devices with the same
identifier.
