SparseTexture clears the first six loaded Mips when the 7th Mip is loaded
Steps to reproduce:
1. Open the attached project (case_1220572.zip) UPDATED version (04/13/2020 dieter.baets)
2. Enter Play Mode
3. Click "Load Image" in the Game View
4. Select the "Lenna.png" image included in the project (Assets/Textures)
5. Click twice on "Load Next Mip" in the Game View
6. Use the slider to ensure that the previous Mips are correct
7. Click "Load Next Mip" four times
8. Repeat steps 6
9. Also validate that unloading mips does not corrupt other mips
Expected result: SparseTexture stores the first six loaded Mips and they are rendered correctly
Actual result: SparseTexture clears the first six loaded Mips and only a black image is rendered.
