CullingResults.visibleLights returns positive light count while there are no visible lights in the camera frustum when oblique camera projection is used

How to reproduce:
1. Open the attached project 'URP_2019.3_b.zip'
2. Notice that there are no lights in the camera frustum in the Scene View
3. Select GameObject > Main Camera GameObject in the Hierarchy
4. Observe Console logs

Expected result: Console logs 'Preview Camera VisibleLights: 0'
Actual result: Console logs 'Preview Camera VisibleLights: 4'

Reproducible with: 2019.4.10f1, 2020.1.5f1, 2020.2.0b2
Not reproducible with 2018.4.27f1 due to errors thrown in the console

- Calculating and oblique matrix from a clip plane aligned with the camera's forward does not yield this problem
- This issue was first observed when using the URP Deferred Renderer that draws from visibleLights. As URP does not support deferred rendering yet it might be a culling issue
