Hi there, I've been experiencing the same issue on similar hardware, and
running libinput-debug-events also results in "edge state:
EDGE_SCROLL_TOUCH_STATE_AREA → SCROLL_EVENT_MOTION →
EDGE_SCROLL_TOUCH_STATE_AREA", when moving in from the sides of the touchpad. 

What I would like to add is previously attached result from a recording by
evemu. When I was recording with evemu, moving my finger from the right off the
touchpad to the center would not move the cursor on the screen at all. But,
when I would playback the evemu recording, the cursor moved as it should have!

In response to your question about POINTER_AXIS events, I have this snippet:
edge state: EDGE_SCROLL_TOUCH_STATE_AREA → SCROLL_EVENT_MOTION →
EDGE_SCROLL_TOUCH_STATE_AREA
gesture state: GESTURE_STATE_UNKNOWN → GESTURE_STATE_SCROLL
event1  POINTER_AXIS     +17.77s        vert 5.81* horiz -1.73*
edge state: EDGE_SCROLL_TOUCH_STATE_AREA → SCROLL_EVENT_MOTION →
EDGE_SCROLL_TOUCH_STATE_AREA
edge state: EDGE_SCROLL_TOUCH_STATE_AREA → SCROLL_EVENT_MOTION →
EDGE_SCROLL_TOUCH_STATE_AREA
gesture state: GESTURE_STATE_SCROLL → GESTURE_STATE_SCROLL
event1  POINTER_AXIS     +17.79s        vert 9.56* horiz -3.37*

I should note that I have edge-scrolling disabled.

Is there anything else I can provide to help? This is only my second time
replying to a bug-report, so I apologize if I'm making some kind of bug-report
faux pas!
