Set Anim Instance Class no longer works with Wheeled Vehicle Pawns

Set Anim Instance Class no longer works with Wheeled Vehicle Pawns

Regression: YES

Worked: 3172292 (4.13.2)
Broken: 3249277 (4.14.3)

1. Create an Advanced Vehicle template project
2. Open the "VehicleBlueprint"
3. Clear the AnimClass for the "Mesh" component
4. Create a key press event in the event graph (I used the P key)
5. Plug it into a "Set Anim Instance Class" node with "Mesh" as the target
6. For "New Class", set the VehicleAnimationBlueprint
7. PIE and drive around with WASD(note no animations play)
8. Hit the key you set for the event and drive around

Result: Still no animations play
Expected: AnimBP is applied and animations now play while driving
