How to reset the position of the caret in the inputfield after the panel has been dragged?

So I have an inputfield that is the child of a panel and the caret inside the inputfield displays properly when the panel is not dragged. After I drag the panel, the caret disappears and never comes back even when I right click on the inputfield again. I can enter text on the inputfield just fine but the only thing missing is the caret. How can I fix this and why does this happen? If it helps, here is the code for dragging a panel.

 using UnityEngine;
 using UnityEngine.EventSystems;
 
 public class DragPanel : MonoBehaviour, IDragHandler
 {
     private RectTransform dragObjectInternal;
 
     [SerializeField]
     private RectTransform dragAreaInternal;
 
     private Vector2 originalLocalPointerPosition;
     private Vector3 originalPanelLocalPosition;
 
     private void Start()
     {
         dragObjectInternal = GetComponent<RectTransform>();
     }
 
     public void OnBeginDrag(PointerEventData data)
     {
         originalPanelLocalPosition = dragObjectInternal.localPosition;
         RectTransformUtility.ScreenPointToLocalPointInRectangle(dragAreaInternal, data.position, data.pressEventCamera, out originalLocalPointerPosition);
     }
 
     public void OnDrag(PointerEventData data)
     {
         Vector2 localPointerPosition;
 
         if (RectTransformUtility.ScreenPointToLocalPointInRectangle(dragAreaInternal, data.position, data.pressEventCamera, out localPointerPosition))
         {
             Vector3 offsetToOriginal = localPointerPosition - originalLocalPointerPosition;
             dragObjectInternal.localPosition = originalPanelLocalPosition + offsetToOriginal;
         }
 
         ClampToArea();
     }
 
     // Clamp panel to dragArea
     private void ClampToArea()
     {
         Vector3 pos = dragObjectInternal.localPosition;
 
         Vector3 minPosition = dragAreaInternal.rect.min - dragObjectInternal.rect.min;
         Vector3 maxPosition = dragAreaInternal.rect.max - dragObjectInternal.rect.max;
 
         pos.x = Mathf.Clamp(dragObjectInternal.localPosition.x, minPosition.x, maxPosition.x);
         pos.y = Mathf.Clamp(dragObjectInternal.localPosition.y, minPosition.y, maxPosition.y);
 
         dragObjectInternal.localPosition = pos;
     }
 }
