contextmenu fires twice on geojson layers

[m00nlighter]

onEachFeature: function(feature, layer){
            layer.bindContextMenu({
            contextmenu: true,
            contextmenuItems: [{
                text: 'Marker item',
                callback: function (e) {
                    console.log(e);
                }
            }]
        });
    layerGroup.addLayer(layer);
    }

its a simple code how to add menu to geojson data(just like in example) but i always get an object without related target in my console.log so i decided to check what return contextmunu.show event.

map.on('contextmenu.show',function(e){
console.log('Context menu fired on :');
console.log(e);
console.log('-');
})

with this code i see that contextmenu fires twice
on first fire it return object with related target
and on second fire it return object without relatedtarget
