Encountered some unexpected behaviour with this snippet:

import nx_arangodb as nxadb
G_adb = nxadb.Graph(
    graph_name="KarateGraph",
    foo="bar",
    bar={"a":4},
)

G_adb.graph["bar"] = {"b": 5} # expecting "bar" to be set to {"b": 5}, but it is {"a": 4, "b": 5}
G_adb.graph["bar"]["b"] = 6 # "b" is now 6, but it has been also duplicated at the top-level of the graph document
G_adb.clear() # Clear the local graph cache (i.e clear G.graph.data)
G_adb.graph["bar"] # fails with KeyError: 'bar'

import nx_arangodb as nxadb
G_adb = nxadb.Graph(
graph_name="KarateGraph",
foo="bar",
bar={"a":4},
)

G_adb.graph["bar"] = {"b": 5} # expecting "bar" to be set to {"b": 5}, but it is {"a": 4, "b": 5}
G_adb.graph["bar"]["b"] = 6 # "b" is now 6, but it has been also duplicated at the top-level of the graph document
G_adb.clear() # Clear the local graph cache (i.e clear G.graph.data)
G_adb.graph["bar"] # fails with KeyError: 'bar'

This behavior got fixed by the commits which will arrive now.
