18902	Polygons are exported to GeoJSON as linestrings	Zverikk	team	"How to reproduce:

1. Create an empty layer.
2. Draw a closed way.
3. Save as GeoJSON.
4. Look inside.

The feature is saved as a LineString, despite it being closed.

Adding ""area=yes"" or even ""natural=water"" does not help — although I'd prefer for polygons to be exported without any properties at all, defaulting to this type with no tags.

This would make JOSM highly useful for maintaining polygon bounds for osmium tool and such."	defect	closed	normal		Core geojson	latest	duplicate	geojson
