ScrollEventFailstoRetrieveMouseCoordinates

In my function handleScroll(e), I attempt to capture the mouse position during a scroll event and use it to schedule an update:

handleScroll(e) {
    // Schedule an update when a scroll event is received.
    // Within a single frame, only the most recent value will be published.
    this.scheduleUpdate({ x: e.clientX, y: e.clientY });
}

I have tested this functionality in Internet Explorer, Firefox, and Chrome, but in all cases, e.clientX and e.clientY return as undefined. For more details, see the following link:

Stack Overflow Discussion

This issue originates from the open-source project ReactJS. Despite reading the documentation, I find it intriguing that this error does not occur with the native touchstart event. I plan to investigate this discrepancy further.
