Blueprints converted to static mesh with negative scales for a component will invert the faces

Negative scaled static mesh components in a blueprint will invert their faces when converted to a static mesh.

Note that this does not happen in the following situations:

• If the BP is scaled negative in the scene the faces will NOT be inverted.
• If you negative scale a static mesh, no blueprint, the faces will NOT be inverted.

Tested in:
Broken: 4.14 Binary CL-3224400
Broken: 4.15 Dev-Editor CL-3239328

Included a screenshot of the converted actor showing the normals not inverted but the faces are.

1. Create a New Blueprint
2. Add any static mesh component to it.
3. Set the scale so negative values for the static mesh component.
4. Add the BP to the scene.
5. Right Click > Convert XX to Static Mesh
6. save the Static Mesh and open the SM Editor or add to the scene

Regression: No

Results: Static Meshes components in a BP that are negative scaled will invert the faces.

Update: Alternate Repro Steps (Since [Link Removed] was determined duplicate)

1. Create a BP and Add a static mesh component
2. Via BP, Set Scale of mesh or root to 1,-1,1 (Any set scale node will repro)
3. Place BP in level, Observe flipped normals.
