The GeoJSON contains an object with property 'overlap' whose value has the unsupported type 'JsonObjectImpl'. That key-value pair is ignored!

[anonymous]

What steps will reproduce the problem?

Load a Geojson file like it.

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {
        "sample": {
          "test1": 1,
          "test2": 2
        }
      },
      "geometry": {
        "type": "LineString",
        "coordinates": [
          [
            110,
            10
          ],
          [
            110.0001,
            10.000001
          ]
        ]
      }
    }
  ]
}

What is the expected result?

The root["features"][0]["properties"]["sample"] is shown in tags/membership.

What happens instead?

JOSM can not recognize root["features"][0]["properties"]["sample"].

The GeoJSON contains an object with property 'overlap' whose value has the unsupported type 'JsonObjectImpl'. That key-value pair is ignored!
