After vertex painting on a Static Mesh component of a Blueprint, the Vertex paint data is lost when the Blueprint is copied.

Oddly, pasting into a text editor shows VertexColorData, but it seems to revert back to the original setting.

Edit MattK: this is probably the component instance data that is not being duplicated

Steps to Reproduce

1. Create an Actor-based Blueprint
2. Add a Static Mesh component and assign a cube
3. Place the Blueprint in a map
4. Go to vertex paint mode and paint some colors on the mesh
5. Ctrl-c to copy the mesh and paste it to the same map or another map

Result: Painted Vertex Colors are now missing
Expected: Blueprint should retain its instance-based Vertex Colors
