panTo() ignores worldCopyJump option

[delner]

I've been developing a web app using Leaflet where the user locates a city by panning to it, then double clicking to place a marker. After the marker is placed, I call the panTo() function to pan the map to the location of the city.

Through the course of this interaction, the user gets a weird experience if they pan around the entire map before panTo() is called:

1. It will rubberband the map around the entire world back to the equivalent place where they started.
2. Any markers on the location in question will 'disappear' (presumably still on a neighboring copy to the center map that Leaflet pans to.)

Here's a video of the interaction I'm seeing. In this case, I'm starting at Los Angeles, scrolling westward around the Earth back to Los Angeles, placing a map marker (the circle that appears before the rubberband), and then calling panTo with the coordinates of Los Angeles. When I call panTo it rubberbands eastward around the world.

I'm not sure whether it qualifies as a bug, but it definitely doesn't feel like great behavior, especially because it "wipes out" map markers in the process. Thoughts?

EDIT:

This is for Leaflet master (1.0.0beta2 + some recent bugfixes)

I was calling panTo() with the following:

leafletMap.panTo([city.lat, city.lng], { animate: true, duration: 1 });

Have you tried the worldCopyJump map option?

I've made a playground showing this bug:

    var mad = [40.40, -3.7];

    var map = new L.Map('map', {center: mad, zoom: 2, worldCopyJump: true});

    var positron = L.tileLayer('http://{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}.png', {
        attribution: '&copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors, &copy; <a href="http://cartodb.com/attributions">CartoDB</a>'
    }).addTo(map);

    var marker = new L.Marker(mad);
    map.addLayer(marker);

    for(var i=1; i<=4; i++) {
        setTimeout((function(a){
            return function(){
                console.log('panning to', [40.40, -3.7 + (90 * a)]);
                map.panTo( [40.40, -3.7 + (90 * a)]);
            }
        })(i), 1000 * i);
    }

    setTimeout(function() {
        map.panTo(mad);
    }, 5000);

Oh, interesting. No I haven't, I'll see if adding the option changes anything.

Yes.
