Prefab Overrides “Apply” button is too big and overlaps with the context menu’s outline

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Cube GameObject (GameObject > 3D Object > Cube)
3. Drag the newly created Cube GameObject to the Project window to create a Prefab
4. Select the Cube GameObject in the Hierarchy window
5. Change the Cast Shadows property to "Off" in the Inspector window
6. Open the Prefab Overrides dropdown in the Inspector window
7. Select "Mesh Renderer" in the dropdown
8. Observe the "Apply" button

Actual results: The "Apply" button is too big, overlapping with the edge/outline of the context menu

Expected results: The "Apply" button is not overlapping with the edge/outline of the context menu

Reproducible with versions: 6000.0.66f1, 6000.3.5f1, 6000.4.0b5, 6000.5.0a5
