Collision between Vehicles and Instanced Meshes are behaving differently than expected

This is a regression tested in //UE4/Release-4.27 CL18319896

Vehicle from the Vehicle template clips through instanced meshes, and can't be driven on them. 

1. Create a new Vehicle template project
2. Create a Blueprint Actor
3. Add an Instanced Static Mesh component to the Actor
   1. Set the Static Mesh to a cube
   2. Under Instances add a new element to the array
   3. Scale the cube so that the car could sit on top of it
   4. Compile, save, and close the Blueprint
4. Place the Blueprint Actor in the world
5. Search for SportsCar_Pawn in the Content Browser
6. Place it above the Instanced Mesh
7. Simulate the scene

Expected Results:
The Vehicle rests on the instanced mesh without the wheels clipping through. If you were to drive the vehicle it would move normally.

Actual Results:
The Vehicle is pressed down against the instanced mesh, and the wheels clip through the mesh. If you drive the vehicle it will not move.
