When alt dragging a skeletal mesh with another actor attached to a socket the relative position of the actor will be set to 0,0,0

When alt dragging a skeletal mesh with another actor attached to a socket the relative position of the attached actor will be set to 0,0,0. The relative offset for the copied attached actor appears to be zeroed out.

1. Download the attached project
2. Open the project
3. Select both the character mesh and the gray cube that is attached
4. Alt+drag the character mesh (and cube) in the project
5. Notice that the boxes relative offset changes for the copy that was created

Expected: The offset for the attached actor would remain the same as the original
Result: The relative offset for the copied attached actor appears to be zeroed out
