Run construction script on Drag set to False has no effect on Vector Variable that use "Show 3D Widget"

If the user has the class defaults of their actor blueprint set for Run construction script on Drag to be false then the vector 3D widget will cause the blueprint to run the construction script anyway when it is moved.

1. Open the editor
2. Create a new actor blueprint
3. Uncheck Run construction script on Drag
4. Create a new vector variable
5. Set variable to editable = True
6. Set Variable to Show 3D Widget = True
7. Drag the widget around
8. Notice that the construction script runs anyway

Expected: The construction script would not run until the vectors 3D widget was done being dragged
Result: The construction script runs when the vectors 3D widget is moved
