Static batching changes Normal map on GameObjects when negative values are used on Scale
How to reproduce:
1. Open the attached "1205209.zip" project
2. Open the SampleScene Scene
3. Enter Play Mode
4. Observe the two Cube GameObjects
Expected result: No changes to the GameObject's when entering Play Mode
Actual result: The right Cube GameObject Normal map changes on Play Mode
Reproducible with: 2017.4.35f1, 2018.4.27f1, 2019.4.9f1, 2020.1.4f1, 2020.2.0a21
Notes:
-This can only work when Static Batching is enabled and the object has negative values on the Scale Transform
-Open Game window in advance to see the changes happening before and after entering Play Mode

Resolution Note (fix version 2020.2):
A new sorting pass that splits out objects with an odd number of negative scales has been implemented. It will result in more batches but normals now renders correctly.
