Describe the bug
After updating from dash 3.0.1 to 3.0.2 or higher, I experience a problem that my geojson from a dynamic dash leaflet control is empty. This is the dynamic control:

            markers_with_edit = dl.FeatureGroup(id={"type": "dynamic_feature", "index": random.randint(3, 9999)},  # noqa: S311
                children=[
                    *markers,
                    dl.EditControl(
                        id={"type": "dynamic_edit", "index": -3},
                        draw={
                            "marker": single_section_selected,
                            "circlemarker": False,
                            "circle": False,
                            "polygon": False,
                            "polyline": False,
                            "rectangle": False
                        },
                        edit={"edit": True, "remove": True}
                    ),
                    dl.EasyButton(id={"type": "dynamic_redraw_button", "index": -4}, icon="fa-retweet", title="Redraw")
                ])

And it is read via this input:

Input({"type": "dynamic_edit", "index": ALL}, "geojson"),

Expected behavior

In my case it should contain some 50 markers, and it does in 3.0.1, but no longer after upgrading
