Line Renderer's Index column in the Positions list has no left padding when the list is expanded in the Inspector

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Line Visual Effect (GameObject > Visual Effects > Line)
3. Select the new Line Visual Effect GameObject in the Hierarchy
4. Open the Positions foldout in the Inspector
5. Observe the Index column

Actual results: The Index column values are flush against the left edge of the list, with no left padding

Expected results: The Index column has the same left padding/margin as other reorderable list columns in the Inspector
