Suggested change
const isVerticalScrolling = Math.abs(event.deltaY) > 3; // This is for touchpads sensitive
if ((event.currentTarget === node) && horizontalOverflow && !isVerticalScrolling) {
if ((event.currentTarget === node) && horizontalOverflow && event.deltaX !== 0) {

What if only do this? What benefit do we get from checking scroll sensitivity?

@parasharrajat Because even if the user scrolls horizontally while scrolling with two fingers on the touchpads, the fingers may go up a little during that scroll, and the page will start to scroll vertically due to this going up. With this sensitive i eliminated this bug.

@parasharrajat and if we only do this event.deltaX !== 0 the scroll will not be smooth. Tested on touchpad.

Ok, I tested it. Looking fine to me. Add a comment instead This is for touchpads sensitive like you did https://github.com/Expensify/App/pull/9026/files#r873936354

@parasharrajat More detailed comment added. PR is ready 👍

node.scrollLeft += event.deltaX;
event.preventDefault();
event.stopPropagation();
