SphereCast returns incorrect collision point for a scaled non-convex mesh

Physics

-

-

Priority: 3Not yet prioritized for a release

-

Severity: 3Secondary functionality broken

To reproduce:
1. Open attached 5.0 project (don't change layout, it makes it easier to notice the problem)
2. Run scene Testscene
3. Move mouse around in game view (If mouse is over the mesh a raycast is calculated to find the collision point. If there is an intersection, it will do a SphereCast to do a sphere collision test.)
4. Notice that the sphere cast will not return the closest collision, but instead it seems to return the first collision that it finds (on screenshots attached it is marked as yellow sphere, green line is an angle between them, which should be around 0 on that surface)

Works fine if mesh is uniform or convex
