Happens in master.

Bisected to 6ca214f + minetest/irrlicht@3992129.

Might depend on build type. I.e. last time I tried, building with sanitizers in Debug build in master, the bug didn't appear.
Reproducible with Release builds.

Summary

Scrolling with mouse wheel in the main menu settings scroll containers seems to only work if you move your mouse while spinning the mouse wheel.

Steps to reproduce

• Open the settings menu.
• Place your mouse cursor in the middle of the screen.
• Spin your mouse wheel.
• => This should scroll the scroll container up and down. But it doesn't work if you hold your mouse still.

I haven't observed this with -DUSE_SDL2=FALSE, so it could be related to the SDL Irrlicht device.
