Error: Invalid LatLng object: (NaN, NaN) #3
Description
In rare edge cases the reference to an old node in a way might be missing in the overpass data which leads to osmtogeojson returning Null coordinates. The creation of the Leaflet layer will fail when Null coordinates are present ('Error: Invalid LatLng object: (NaN, NaN)'). Thus we filter them out here.
Below is an example xml file which has been fetched from Overpass. Node 5727511182 does not have coordinates in 'old' which leads to the problem described above.
