Objects with instanced shaders handle shadow casting incorrectly once negatively scaled

Shaders

-

Repro steps:
1. Open "InstancedShadowCasting" project
2. Load "Scene" scene
3. Observe that objects with instanced shaders once negatively scaled start to handle shadow casting incorrectly.
Note: You can also scale down plane next to (1,-1,1) negatively to see shadow jump next to (1, 1, 1) plane.
User attached a GIF.

Actual behavior: Objects with instanced shaders handle shadow casting incorrectly once negatively scaled, shadows jump to another object.
Expected behavior: Objects with instanced shaders should handle shadow casting correctly, no jumping shadows.

Reproduced on: 5.4.0f3, 5.4.0p1, 5.5.0a6

    Shadows do not "jump to another object" at all. The included scene has pairs of planes, and the directional light casts shadows from both: the actual behaviour is that the shadows are being casted from an incorrect side of a mesh once it's negatively scaled.

    On this gif, you see the included scene in full. Only the invisible quads, ones facing the sun, not the camera, leave the shadow. The bug allows a sun-facing quad to stop casting the shadow and allows a camera-facing quad to start casting a shadow. That's the gist of it. :)
