Custom Attribute list items are misaligned in Graph Inspector

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create and open any Shader Graph (Assets > Create > Shader Graph)
3. In the Shader Graph blackboard, click the + icon
4. Select "Vector3" (or any other that has Custom Attributes property)
5. Select the newly created "Vector3"
6. In the Graph Inspector, find the Custom Attributes property
7. Add a few items to the list
8. Select any added item by clicking the reordering icon
9. Observe the Value field

Actual results: The Value input field is misaligned/stuck to the top and not centered

Expected results: The Value input field is fully centered

Reproducible with versions: 6000.0.65f1, 6000.3.3f1, 6000.4.0b3, 6000.5.0a4

Tested on (OS): Windows 11

Notes:

• Selecting the item is not necessary to observe the misalignment, but it becomes easier to see
• I believe this also affects the Name field, but it is not as observable
