Reproduction steps:
1. Open project in "2020.1.0a17.zip"
2. Open "SampleScene.unity"
3. Notice that there are 2 Cubes in Scene which have Different Layers L1 and L2
4. Notice that ForwardRenderer renders nothing but these two Layers L1 and L2 using Renderer Features
5. Notice that Camera is in Orthographic mode
6. Toggle Camera Override for the first Renderer Feature in list using ForwardRenderer

Expected result: Camera override applies only for the Object that is in Layer L1
Actual result: Camera override applies for both GameObjects

Reproducible with: LWRP 6.9.0 (2019.2.18f1), URP 7.1.6 (2019.3.0f4, 2020.1.0a17)
Could not test with: 2017.4, 2018.4 because these versions do not support URP 7.1.1 and above

Notes:
1. The issue reproduces only when Camera Override is toggled for the first element in Renderer Features list and works as intended when toggling it for other elements
2. First URP version to support Renderer Features is URP 7.1.1
