Some Prefab Source section items overflow into Override section

Reproduction steps:
1. Create a new project
2. Create a new GameObject and add a LOD Group Component in Inspector (Rendering > LOD Group)
3. Create a Prefab by dragging GameObject into the Project window
4. Select newly created GameObject and change any of the LOD Group Component fields values
5. Click on Overrides dropdown in the Inspector and click on LOD Group section
6. Observe the Prefab Source section items

Actual result: “Recalculate Lightmap Scale” and “Reset Object Size” buttons overflow into Override section
Expected result: “Recalculate Lightmap Scale” and “Reset Object Size” buttons stay in Prefab Source section
