The scene includes two base cameras. As expected, the output from the second base camera overwrites first base camera's output. For more details, refer to the camera stacking documentation: https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@16.0/manual/camera-stacking.html

How to reproduce:
1. Open the attached “IN-103359.zip” Project
2. Open the “SampleScene”
3. Enter Play Mode
4. Observe the Game View

Expected result: A Cube GameObject and a Yellow Background is visible
Actual result: A Sphere GameObject and a Yellow Background is visible
