Description

Hi!

I noticed that dragging a route throws a JS error as in layer.js in line 291 this._routePolyline()._originalPoints; is undefined.

It seems that _originalPoints is not available anymore in newer Leaflet versions. I was able to fix it by converting the latlngs:

var positions = this._routePolyline()._latlngs;

for (var j = 0; j < positions.length; j++) {
    positions[j] = this._map.latLngToLayerPoint(positions[j]);
}

Best regards,
Michael

Research direction

Start in layer.js at line 291 and inspect how the route polyline is used during dragging. Compare the unavailable _originalPoints access with the route polyline's _latlngs and verify that dragging a route no longer throws the reported JavaScript error.
