[HDRP] Mesh is not rendered when it is using HDRP Tessellation Shader and is Viewed from a certain perspective

Package: Scriptable Render Pipeline HD

-

How to reproduce:
1. Open the attached project named "Case_1299116"
2. Open the OutdoorsScene
3. Observe the Game View - the Base gameObject is rendered
4. Select the Static/Base gameObject's material and change the used shader to HDRP/LitTessellation or HDRP/LayeredLitTessellation
5. Observe the Game View again

Expected results: The gameObject is rendered
Actual results: The gameObject is not rendered

Reproducible with: 7.5.2(2019.4.18f1), 10.2.2(2020.2.2f1), 11.0.0(2021.1.0b1)
Could not test with: 2018.4(HDRP was in early preview stage)

Notes:
1. The gameObject is not rendered only from specific angles. If the Camera is moved slightly, the object will be rendered
2. Occurs in the Scene view as well as Game view
3. Tested with graphics APIs - D3D11, D3D12, Vulkan
4. Base gameObject was generated using ProBuilder, however, this can be reproduced when using identically sized built-in primitive shapes. Tested using a simple Cube stretched to the same dimensions and it would also be not rendered
