The construction script for a custom actor blueprint does not execute after drag when the scene component is selected.
Tested in 4.21.2 (CL - 5660361), 4.22.1 (CL - 6063286), 4.23 (CL - 6248266)
Expected: The print string should still execute after movement
Result: The construction script is ignored and not fired after the drag action has completed
