Description:
Whether I use the mouse with horizontal scroll, or two fingers on the trackpad, horizontal scroll always has wrong direction. 
Per example - if in OS setting I choose natural scroll, then vertical scroll IS natural (i.e. rolling the wheel down, the document pans down), but horizontal scroll ISN'T (i.e. rolling the wheel to the left, the document pans right). If in OS setting I don't choose natural scroll, then vertical scroll ISN'T natural (i.e. rolling the wheel down, the document pans up), and horizontal IS natural.

The problem is the same in Calc and in Writer

Steps to Reproduce:
1. open a document in Calc od Writer
2. zoom so that the width of the document doesn't fit in window
3. try to scroll up-down and left-right using a mouse ball/track surface or trackpad surface

Actual Results:
The horizontal scroll always goes the wrong way

Expected Results:
The horizontal scroll should go in the direction chosen in OS settings (natural direction or not natural direction), like vertical scroll does 


Reproducible: Always
