Dragging category-select options in long lists freezes and misplaces items while reordering

When reordering options in a long single-select list, dragging an item causes the list to freeze visually and the item’s apparent position can drift out of sync with the mouse/scroll position. This makes it difficult to place items accurately and often requires multiple drag attempts to get the item into the correct spot.

Steps to Reproduce

  1. Open a single-select field with a long list of options in edit mode (I’ve had this in legacy and new record types).
  2. Start dragging an option from near the top of the list downward.
  3. While dragging, scroll the list using the mouse wheel or trackpad.
  4. Observe that the list appears to freeze or the dragged item’s visible position does not match the scroll position.
  5. Release the mouse and note that the item may land in an unexpected position, requiring additional drag attempts to place it correctly.
