--- Comment #4 from Peter Hutterer <peter.hutterer at who-t.net> ---
Found it, patch available on the list:
https://lists.freedesktop.org/archives/wayland-devel/2017-March/033258.html

FTR, the triggering sequence is around
  E: 4.227286 0003 0035 1828      # EV_ABS / ABS_MT_POSITION_X    1828

The pressure goes below the threshold, switching the touch to end, then hover/
The actual end event is papered over this way (as seen and by the button state
machine), the button state triggers on the current position (1828/803) which is
in AREA. When the new touch comes down in 1756/1769 we're already in state AREA
and don't update, hence the left button click despite these coordinates being
in the middle button area.
