Bug in CorridorGeometry

[hpinkos]

The CorridorGeometry doesn't line up with the Polyline that has the same points. I suspect the root of the problem is that some of the points are colinear-ish.

var viewer = new Cesium.Viewer('cesiumContainer');

var points = Cesium.Cartesian3.fromDegreesArray([
    15.966388702392578, 46.84194564819336, 
    15.938333511352539, 46.66777801513672,     
    15.8797221183776855, 46.3025016784668, 
    16.390833377838135, 45.80833435058594,
    16.746944427490234, 45.45722198486328, 
    16.940000057220459, 45.26444625854492
]);

for (var i = 0; i < points.length; i++) {
    viewer.entities.add({
        position : points[i],
        point : {
            color : Cesium.Color.YELLOW,
            pixelSize : 10
        }
    });
}

viewer.entities.add({
    corridor : {
        positions : points,       
        width : 50000,
        material : Cesium.Color.BLUEVIOLET.withAlpha(0.5)
    }
});

viewer.entities.add({
    polyline : {
        positions : points,
        width : 2,
        material : Cesium.Color.CYAN
    }
});
