# We could use @export_custom to really test every property usage, but we know for good
# that duplicating scripted properties flows through the same code already thoroughly tested
# in the [Resource] test cases. The same goes for all the potential deep duplicate modes.
# Therefore, it's enough to ensure the exported scriped properties are copied when invoking
# duplication by each entry point.
