Better support for an inertia wheel mouse / smooth scroll?

Hello. I would like to know if it is possible to add smooth (non-step) scrolling to GTK.ScrolledWindow?

In the browser (Chromium) with GTK3, scrolling goes smoothly, but in apps that use GTK4, scrolling goes in steps even if inertia mode is enabled on the mouse.

I will be glad to hear the answer.
