It's not supported yet. Sadly, for performance reasons, we can't use the native browser scrolling and what basically need to build our own so called "virtual scroller".
It will probably come at some point, but for now there are a lot more impactful changes that we can do with 1/10 of the development time of that.
That said, you can just keep the tab key pressed, which allows you to go down/up really fast, after all, the goal is to not use the mouse if possible 😃
