Leaflet.Snap无法将折线捕捉到guideLayer

Question

我在绘制新的折线时尝试在guideLayer上捕捉折线点。当我接近它时，我的鼠标会与guideLayer对齐，但我无法在guideLayer上添加新点。

我的地图和控件声明如下：

var mymap = L.map('map').setView([46.658, 7.011], 14);
var drawnItems = new L.FeatureGroup();         
var mymap.addLayer(this.drawnItems);
var tracksGeoJson = L.geoJSON(listTracks).addTo(mymap);
var guideLayers = [tracksGeoJson];

var drawControl = new L.Control.Draw();
var drawControl.initialize({
    edit: {
        featureGroup: drawnItems 
        },
    draw: {
        polygon: false,
        circle: false,
        rectangle: false,
        marker: false,
        polyline: {guideLayers: display.guideLayers, snapDistance: 10}
    }
});
mymap.addControl(this.drawControl);      

我使用Leaflet v1.0.3，Leaflet.draw v0.49和Leaflet.Snap v0.0.4。

我找到了它！

“snapDistance”选项对折线不起作用。所以新的drawControl初始化是：

var drawControl = new L.Control.Draw();
var drawControl.initialize({
    edit: {
        featureGroup: drawnItems 
        },
    draw: {
        polygon: false,
        circle: false,
        rectangle: false,
        marker: false,
        polyline: {guideLayers: display.guideLayers}
    }
});
mymap.addControl(this.drawControl);

现在我可以在其他折线上添加折线点。
