When scrolling the mouse wheel on the desktop, the workspace changes. However
when moving the mousewheel upwards, the workspace moves one downwards, which is
not logical.

Perhaps some people like this behaviour, but what about some (hidden) config option?

Reproducible: Always
Steps to Reproduce:
1. Point mouse at desktop backdrop
2. move mouse wheel
3. 

Actual Results:  
When I'm at my first workspace (the most left in the pager), and I move my
mousewheel upwards while pointing on the desktop, it actually switches to my 5th
workspace.

Expected Results:  
Switch to my 2nd workspace which would make more sense (mousewheel up =>
workspace up).
