3. Enter "Play" mode
4. Observe the cube in the Game view
Expected outcome: The cube is not surrounded by a light-leaking quare
Actual outcome: the cube is surrounded by a light-leaking square

Resolution Note:
This is not light leaking but a fallback to the ambient probe when a pixel tries to sample APV outside of the APV structure. This behavior is expected.
To remove the artifact (a square here), the ambient probe and the lightbaking settings should match. You can do so by setting 'static' for the ambient mode, in a Visual Environment volume override.
