Scaling Issue with the Web view

I have developed a code for dragging for a panel in unity 3d ; But, That codes are not working with this Web view .. can i know a solution where i can make it ??

public class Dragpanel : MonoBehaviour
{
    // Start is called before the first frame update
    float OffsetX;
    float OffsetY;
    public void BeginDrag()
    {
        OffsetX = transform.position.x - Input.mousePosition.x;
        OffsetY = transform.position.y - Input.mousePosition.y;
    }
    public void OnDrag()
    {
        transform.position = new Vector3(OffsetX + Input.mousePosition.x, OffsetY + Input.mousePosition.y);
    }
}

Start by reproducing the issue with the Dragpanel class and its BeginDrag and OnDrag methods in the Unity web view. Compare the panel's coordinate and scaling behavior during dragging, including the web view's target platform and input handling. Done means the panel can be dragged reliably at the intended scale.
