geojson point change circle marker to icon

hello gays
i use this in my code,

var tile = L.vectorGrid.slicer(geojson,{
                    interactive: true,
                    rendererFactory: L.canvas.tile,
                    vectorTileLayerStyles:{
                        sliced: { icon: new L.Icon.Default()}
                    }
                    }).addTo(map);
tile.on('click', function(e) {
                        var pro = e.layer.properties;
                        var HTML = '';
                        for (var q in pro) {
                            HTML += q + ":" + pro[q] + '<br />';
                        }
                        L.popup()
                            .setContent(HTML)
                            .setLatLng(e.latlng)
                            .openOn(map);
                    })

thx

Start with the linked Plunker reproduction and the L.vectorGrid.slicer configuration shown in the issue, focusing on the icon hover path that produces the undefined-lat error. Confirm the failure with Leaflet 1.2.0 and determine what needs to change so moving over the point icon no longer throws the error.
