Duplicating inherited variables in the MyBlueprint panel doesn't copy data from the old variable to the new variable

Duplicating inherited Blueprint variables should copy the data from the original variable to the duplicated variable.

• Create a Blueprint (BP_Parent) and add a FString variable (MyString) with some test data.
• Create a child Blueprint (BP_Child) derived from BP_Parent.
• In the MyBlueprint panel of BP_Child, right click the MyString variable and click duplicate
• Note that a new variable of type FString is created, but the data is not duplicated
