Subject: [PATCH] wayland: Pass the inverted flag for horizontal scroll events

Natural scrolling affects both axes, and the compositor may not send the vertical axis orientation if the frame has no vertical scroll motion, so purely horizontal events need to be flagged as inverted as well.

(cherry picked from commit 3ee0439ae508671ec9e5dc54b4a3e59105ad6972)
