layer on click event not always fired when a popup is used

[Evgeny Kleiman]

I have the a layer with on click handler:

countriesLayer = L.geoJson(ct,

   {

       style: myStyle,

       onEachFeature: onEachFeature

   }

   )

 function onEachFeature(feature, layer) {

    var center = setLabelCenter(layer);

    feature.center = [center.lng, center.lat];

    layer.on({

            click: onFeatureClick,

             mouseover: showMapTip,

    });

Also I have a popup for mouse over:

 function showMapTip(e) {

        var layer = e.target;      

        var content = getInfoContent(layer.feature.properties);        

        layerPopup = L.popup( {

                      autoPan : false

            })

        .setLatLng(e.latlng)

           .setContent(content)

           .openOn(mymap)

    }

The problem is that onClick event is not always fired. More exactly, it is fired in about 10% cases. If I cancel popup the it works.

Is it possible to solve the problem?
