Corset Model Contains a Flipped Polygon in Front of the Surface

The Corset model appears to contain an incorrectly placed interior polygon that protrudes through, or lies in front of, the visible exterior surface. During path-traced rendering, the camera ray hits the exterior front-facing surface first, so the misplaced polygon is not visible directly. However, shadow rays still intersect this flipped or internal polygon, causing an incorrect shadow patch on the model.

The following visuals were rendered with [vk_gltf_renderer](https://github.com/nvpro-samples/vk_gltf_renderer).
