Camera's depth is ignored when calling Camera.Render() for Render Texture with "Skybox" and "Dont Clear" cameras

How to reproduce:
1. Open attached project "Depth Clear Test.zip" and scene "SampleScene"
2. Enter play mode
3. Observe the Game view

Expected result: the blue square is visible and behind the green square
Actual result: blue square is visible and in front of the green square

Reproducible with: 2017.4.38f1, 2018.4.20f1, 2019.3.6f1, 2020.1.0b2, 2002.2.0a3

Resolution Note:

This is part of the built in renderer camera stacking. We can not change this behaviour now at risk of regressing many users projects.

Workaround: have the 'render texture' settings match the current quality settings (msaa and color format)

Well that's BS. Not only is it extremely unlikely that "many users" are using Camera.Render() into the same render texture as another camera with the clear flags mistakenly set to "Don't Clear" when they actually want "Depth Only", the built-in renderer's camera stacking cannot possibly rely on the hack of ignoring the "Don't Clear" flags for manual rendering only but not for automatic rendering! That's nonsense! Please review and make sure you've fully understood the problem!
