Bug: including `Touchpad` device prevents cursor movement

Requirements

I've searched platform-specific issues, issues and discussions to see if this has been reported before.
My issue does not involve multiple simultaneous key presses, OR it does but I've confirmed it is not key rollover or ghosting.

Describe the bug

In my linux-dev-names-include I list the following "mouse" (touchpad) device:

12:29:32.8528 [INFO] device [/dev/input/event6:ELAN0735:00 04F3:316C Mouse] is included

This does not cause any issues, but also does not seem to pull in any events. Running in --debug shows no output when moving around the touchpad, or clicking any combination of fingers. Maybe it's just a dummy device of some kind, I'm not sure.

So I then attempted to include the other device associated with my touchpad hardware:

 12:29:32.8528 [INFO] device [/dev/input/event6:ELAN0735:00 04F3:316C Touchpad] is included

At first I tried running without sudo per the doc instructions (how I usually run Kanata), but the device does not get listed as included despite being in my config. When I run Kanata with sudo, I get the above is included message. However, my cursor stops responding to touchpad movements. I can still press to click, but tapping does not click and moving around the touchpad does not move the cursor. process-unmapped-keys is on, and I've tried switching to linux-output-device-bus-type USB as well. It's definitely processing input from the device per the DEBUG logs, but movements don't seem to pass through.

Relevant kanata config

(defcfg
  process-unmapped-keys yes
  delegate-to-first-layer yes
  rapid-event-delay 5
  movemouse-smooth-diagonals yes
  movemouse-inherit-accel-state yes
  mouse-movement-key mvmt
  ;; Kanata captures everything on Linux by default, so we give it these device names as to ignore the rest.
  linux-dev-names-include (
    "ELAN0735:00 04F3:316C Mouse" ;; no input
    "ELAN0735:00 04F3:316C Touchpad" ;; consumes cursor movement
    "AT Translated Set 2 keyboard"
    "Logitech G305"
    "Razer Razer DeathAdder Essential"
    "Razer Razer DeathAdder Essential Keyboard"
    "ZMK Project Lily58 Mouse"
    "ZMK Project Lily58 Keyboard"
    "Lily58 Mouse"
    "Lily58 Keyboard"
  )
)

To Reproduce

Attempt to include this touchpad. I have no other touchpad hardware to test with, unfortunately.

Expected behavior

Cursor continues to move while touchpad is included.

Kanata version

1.12.0

Operating system and I/O mechanism

Linux

Additional context

I'm attempting to get an automousekeys layer set up and was hoping mvmt would work by including it.
