Horizontal scroll event not firing for react window

Question

OnScroll events are not firing for a horizontal scrollbar in list implementation of react-window.

Minimal replication is at - https://codesandbox.io/s/summer-https-dyhvu

In the given example we can see that for native implementation both horizontal and vertical scroll events are fired(check console)

In a react-window implementation of a list, only vertical(which is virtualized) scroll events are fired, not the horizontal ones.

Is there a way to fire the event for horizontal scroll event for a vertically virtualized list?

Answer 1

After digging found solution using outerRef prop on List and attaching custom scroll event to it.
