Regression
Yes
[Universal RP] Stencil buffer is cleared when disabling SSAO and/or Depth Texture
How to reproduce:
1. Open the user's attached project "HighlightTest.zip"
2. Open Game View
3. Select "ForwardRenderer" (Assets > Repro > URP Settings) and disable SSAO
4. Observe changes in the sphere GameObject's glow
Expected result: Sphere GameObject's outer glow is behind the GameObject
Actual result: Sphere HameObject's outer glow is in front of the GameObject
Reproducible with: 12.0.0 (2021.2.0b2), 12.1.6 (2021.2.19f1), 13.1.1 (2022.1.0a16)
Not reproducible with: 7.7.1 (2019.4.37f1), 10.8.1 (2020.3.33f1), 12.0.0 (2021.2.0b1), 13.1.3 (2022.1.0b1), 13.1.7 (2022.1.0b15), 14.0.2 (2022.2.0a10)
Notes:
- Disabling Depth Texture in "UniversalRenderPipelineAsset" (Assets > Repro > URP Settings) when SSAO is disabled will not reproduce the issue
- Disabling Anti Aliasing (MSAA) in "UniversalRenderPipelineAsset" after disabling SSAO and/or Depth Texture will not reproduce the issue

Resolution Note:
This behavior is by design as setting SetRenderTarget at the start of the render feature eliminates the issue. As discussed here: https://unity.slack.com/archives/CAR8G94EL/p1646140659190639
