Selecting a mipchain for a texture means that we are generating it offline during the build process. It does not mean that we use the automatic mip generation of DX11 that also requires the texture to be set as a rendertarget, which would have performance implications.

How to reproduce:
1. Open the attached project "NativePlugin.zip"
2. Open Assets/scene.unity
3. Open NativePlugin\PluginSource\projects\VisualStudio2015\RenderingPlugin.sln
4. Open "RenderAPI_D3D11.cpp" in the Solution Explorer
5. Add breakpoint at line 261
6. Click Debug>Attach to Process...
7. Select "UnityProject - scene" in the Attach to Process window
8. Click Attach
9. Enter Play Mode in the Unity Editor
10. Step Over (F10) 3 times in the Visual Studio

Expected results: miscFlag = 1
Actual results: miscFlag = 0

Reproducible with: 2020.3.47f1, 2021.3.23f1, 2022.2.16f1, 2023.1.0b14, 2023.2.0a12
