+Subject: [PATCH libinput] touchpad: only edge-scroll while the finger is in
+ the edge area
+
+When the touch leaves the area for edge scrolling after starting to scroll,
+discard any movement. This signals to the user that they've left the area and
+forces them to lift the finger to switch back to motion. If the finger moves
+back into the area, scrolling continues.
