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.
