1) What happened
Universal shader: incorrect shading of scaled in one dimension spheres/capsules

2) How can we reproduce it using the example you attached
1. Create a sphere or capsule within default scene settings
2. Scale it on X only to some large value (e.g. to 5)
---> Shaded side of the object starts on actual top of the object (on the lit side)
See attached project. There's a capsule in this project with legacy diffuse shader to see the difference.
