Description

To replicate:

1. Create a Process Group named Parent
2. In that Process Group, create a new Process Group named Child
3. In Child, add an Input Port, a Processor such as UpdateAttribute, and an Output Port. Connect them together.
4. In Parent, create a GenerateFlowFile and connect it to the Child input port
5. Version Control Child
6. Version Control Parent
7. Move the UpdateAttribute Processor in Child. Save next Version
8. Move UpdateAttribute again. Save next Version
9. Save version of Parent
10. Remove Connection from GenerateFlowFile to Child Input Port
11. Change Child from Version 3 to Version 1
12. Change Child from Version 1 to Version 3
13. View Local Modifications in Parent. We should see only that the connection was removed, but it's showing all components in the child group as newly added.
