Lorem Ipsum

SUMMARY
Mouse scroll wheel in single page mode doesn't switch page anymore. It was
working just fine until it broke recently.

STEPS TO REPRODUCE
1. Open a PDF file with Okular which has several pages. I attached a "Lorem
Ipsum" just for reference.
2. Set View Mode to "Single Page"
3. Set Zoom (?) to "Fit Width"
4. Rotate the mouse wheel in order to switch to the next page. One click of the
wheel should switch the page.

OBSERVED RESULT
The page is not switched when I rotate the mouse wheel. 

EXPECTED RESULT
The page is switched with 1 click of the wheel into the corresponding
direction.

ADDITIONAL INFORMATION

As I said, this feature was working fine before on my system. It broke after an
update.

Page switching works with another cheap USB mouse. I am unable to investigate
the issue further as I am not familiar with the internals of Okular nor Wayland
nor Mouse drivers nor whatever else may be responsible.
