Dynamic zoom -zg not being able to generate tiles for a small data feature

[MariaSliacka]

Hello, we noticed that when using the -zg option, we are unable to generate tiles for a very small data, such as the geojson below that contains just one line. But using -z15 on that same data produces tiles as expected. See the command and the output below the geojson. Is there any workaround or a fix that we could use to make the tiler works with the -zg option?

        {

            "geometry": {
                "type": "GeometryCollection",
                "geometries": [
                    {
                        "type": "MultiLineString",
                        "coordinates": [
                            [
                                [
                                    -2.46099426,
                                    56.70343111
                                ],
                                [
                                    -2.46084165,
                                    56.70159985
                                ]
                            ]
                        ]
                    }
                ]
            },
            "properties": {
                "layer_name": "ESCA_CABLE"
            }
        }
    ],
    "crs": {

        "properties": {
            "name": "EPSG:4326"
        }
    }
}

When using -zg, the chosen max zoom is 1 but it actually only generates the metadata file:

% tippecanoe --drop-smallest-as-needed --no-tile-compression -S10 --simplify-only-low-zooms -zg --layer=geojson -e tests/small_layer small_layer.geojson
error_layer.geojson: Warning: GeoJSON specified projection "EPSG:4326", not the expected "urn:ogc:def:crs:OGC:1.3:CRS84".
error_layer.geojson: If "urn:ogc:def:crs:OGC:1.3:CRS84" is not the expected projection, use -s to specify the right one.

But when using for example -z15 it generates all the tiles as expected:

% tippecanoe --drop-smallest-as-needed --no-tile-compression -S10 --simplify-only-low-zooms -z15 --layer=geojson -e tests/small_layer small_layer.geojson
