Rectangle bounds with WGS84/EPSG4326 don't align perfectly

[teslash21]

Hi,

I’m creating a Cesium Rectangle with bounds in WGS84 / EPSG4326 system. But there are a lot of misalignments and they don’t perfectly align as they did with mapbox-gl-js or deck.gl. Can anyone please take a look and tell me what is wrong?

        const rasterSuperImposeLayer = new Cesium.Entity({
            id: "raster-layer",
            name: "Raster Layer",
            rectangle: {
                coordinates: Cesium.Rectangle.fromDegrees(
                    ESA_BOUNDS[0][0], // West
                    ESA_BOUNDS[3][1], // South
                    ESA_BOUNDS[2][0], // East
                    ESA_BOUNDS[1][1]  // North
                ),
                material: new Cesium.ImageMaterialProperty({
                    image: new Cesium.ConstantProperty(simulationLayerData.toString()),
                    transparent: true,
                    alpha: 0.4,
                }),
                clampToGround: true,
                show: true,
            },
            show: true,
        });
        console.log("Adding new raster layer: ", rasterSuperImposeLayer);
        viewer.entities.add(rasterSuperImposeLayer);
