Expected Behavior
It should not be possible to create an infinite recursion of sceneitems.

Steps to Reproduce
- Create Scene A
- Create Group A inside Scene A
- Create Scene B
- Add Scene A and Group A as sceneitems in Scene B
- In the "Sources" dock, drag and drop Scene A into Group A
- Crash

Research direction
Reproduce the crash using the listed Scene A, Group A, and Scene B drag-and-drop steps, then inspect the OBS Studio log at the provided URL. Trace how a scene can be inserted into a group within that scene. Done means the invalid infinite-recursion nesting is prevented and OBS no longer crashes.
