[REQUIRED] Step 1: Describe your environment

• Unity version: 2022.3.50f1
• Google Mobile Ads Unity plugin version: 9.4.0
• Plugin installation method: Unity package manager
• Platform: iOS
• Platform OS version: iOS 18.1.1
• Any specific devices issue occurs on: no
• Mediation ad networks used, and their versions: none

[REQUIRED] Step 2: Describe the problem

On iOS, Unity Input Events, such as OnBeginDrag, OnDrag, OnEndDrag were called when the user swiped on the native overlay ad.
Is this specification or bug?
On Android, input events on the native overlay ad are not notified to Unity.

In addition, the argument of the Unity input events, PointerEventData, was improper.
PointerEventData.position.y was set -7126225000.

I want Input Events on the native overlay advertisement be not notified to Unity, like Android.
Or,I want to get the correct PointerEventData.

Steps to reproduce:

Step1. Render a native overlay ad on the scroll rect.
Step2. Swipe up and down on the ad.
Step3. Verify that Unity Input Events are called and PointerEventData.position.y is improper.

    public class HomeScroller : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler
    {
        public void OnBeginDrag(PointerEventData eventData)
        {
            Debug.Log("OnBeginDrag: eventData.position = " + eventData.position);
        }

        public void OnDrag(PointerEventData eventData)
        {
            Debug.Log("OnDrag: eventData.position = " + eventData.position);
        }

        public void OnEndDrag(PointerEventData eventData)
        {
           Debug.Log("OnEndDrag: eventData.position = " + eventData.position);
        }
    }
