[nemesifier]

Remove this code:

openwisp-monitoring/openwisp_monitoring/device/static/monitoring/js/device-map.js

Lines 360 to 391 in 6f6fd7e

	// When panning west past the dateline, clone features shifted −360°
	if (bounds._southWest.lng < -180 && !netjsonGraph.westWorldFeaturesAppended) {
	const westWorld = structuredClone(netjsonGraph.data);
	westWorld.features = westWorld.features.filter(
	(f) => !f.geometry || f.geometry.coordinates[0] <= 180,
	);
	westWorld.features.forEach((f) => {
	if (f.geometry) {
	f.geometry.coordinates[0] -= 360;
	}
	});
	netjsonGraph.utils.appendData(westWorld, netjsonGraph);
	netjsonGraph.westWorldFeaturesAppended = true;
	}
	// When panning east past the dateline, clone features shifted +360°
	if (bounds._northEast.lng > 180 && !netjsonGraph.eastWorldFeaturesAppended) {
	const eastWorld = structuredClone(netjsonGraph.data);
	eastWorld.features = eastWorld.features.filter(
	(f) => !f.geometry || f.geometry.coordinates[0] >= -180,
	);
	eastWorld.features.forEach((f) => {
	if (f.geometry) {
	f.geometry.coordinates[0] += 360;
	}
	});
	netjsonGraph.utils.appendData(eastWorld, netjsonGraph);
	netjsonGraph.eastWorldFeaturesAppended = true;
	}
	});
	},
	});

In favour of openwisp/netjsongraph.js#466 (needs to be merged first)
