           Summary: Scroling direction is inconsistent between horizontal
                    and vertical scrolling when using the scroll wheels
                    the mouse
    Classification: Plasma

SUMMARY
When using a mouse that has a dedicated horizontal scroll wheel like the
Lotitech MX Master series has, the scrolling direction of the horizontal and
vertical scrolling is inconsistent.

When "inverted scrolling" is disabled:
Scrolling vertically moves the scrollbar in the same direction as the finger on
the mouse wheel
Scrolling horizontally moves the scrollbar in the *inverted* direction of the
finger movement

Activating "inverted scrolling" switches both options around:
Scrolling vertically moves the scrollbar in the *inverted* direction of the
finger movement
Scrolling horizontally moves the scrollbar in the same direction as the finger
on the mouse wheel

EXPECTED RESULT
When "inverted scrolling" is disabled, both scrolling directions should be
moving the scroll bar in the direction of the finger and when "inverted
scrolling" is enabled, both scroll directions should be moving the scroll bar
in the direction opposed to the finger movement.

I think ideally, there should be dedicated settings for "inverted vertical
scrolling" and "inverted horizontal scrolling" so users can mix and match to
get their ideal scrolling style.
