Base commit: e84268a (image tag)
Issue: Nested dictionaries in `py/state` incorrectly restored when tracking object references Repro: ```python import jsonpickle class MyClass: def __init__(self, o):

Files to edit

jsonpickle/unpickler.py

Approach: In _restore_state, after extracting and applying py/state, add early return when py/restore exists so reconstruction happens exactly once.
