Depth buffer rendering skybox incorrectly
How to reproduce:
1. Open the attached project
2. Open the "SetMatrixArrayBug.unity" scene
3. Check how Quad is rendered in the Game view
Actual result: Quad is rendered over the cube, but not over the skybox. (screenshot attached)
Expected result: Skybox should always be rendered behind everything else.
Reproducible with: 2017.4.32f1, 2018.4.8f1, 2019.2.5f1, 2019.3.0b3, 2020.1.0a4.
Notes:
- Changing camera "Clear Flags" mode to anything else causes the quad to render correctly.

Resolution Note (fix version 2019.3):
The shader for the skybox indeed has a render queue of 1000.
But, this is not used in the game view window, as described by the documentation here: https://docs.unity3d.com/Manual/SL-SubShaderTags.html
"Queues up to 2500 (“Geometry+500”) are consided “opaque” [...] Skyboxes are drawn in between all opaque and all transparent objects."
Possible solutions to ensure drawing over skybox are:
- use ZWrite On with ZTest Always in the shader
- or specify render queue 2501 or more.
