Cannot scroll on Ditto Menu using touch screen

[archisman-panigrahi]

I have a touch screen laptop running Arch Linux KDE.
After opening Ditto Menu, I cannot scroll on it using the touch screen to browse apps (scrolling with touch screen just works fine).

When I try to scroll with a single finger on the touch screen, the apps are selected instead.

Scrolling (with a single finger on the touch screen) works perfectly on apps like Dolphin and Okular, so I guess that KDE has frameworks to support it.

It would be great if ditto menu supports scrolling using touch screen.

By the way, scrolling with touch works on OnzeMenu!

A weird question: does it work in any other scrollable section apart from All Apps?

I unfortunately have the same issue in Plasma 5 / Kubuntu, could this feature be added and backpirted to the plasma 5 Ditto menu too?
