Leaflet: GeoJson pointerEvents = 'none' any effects

• [X] I'm reporting a bug, not asking for help
• [X] I've looked at the documentation to make sure the behaviour is documented and expected
• [X] I'm sure this is a Leaflet code issue, not an issue with my own code nor with the framework I'm using (Cordova, Ionic, Angular, React…)
• [X] I've searched through the issues to make sure it's not yet reported

How to reproduce

• Leaflet version I'm using: 1.0.3
• Browser (with version) I'm using: Chrome 55
• OS/Platform (with version) I'm using: Windows

What behaviour I'm expecting and which behaviour I'm seeing

I have to display two GeoJson overlays : one which can interact with user (click, mouse over) and the second with non interaction, just for displaying visual information.
The first layer is under the second and only the stroke has to be drawn.

I have specify "pointerEvents" to none for the second layer style, but LeafLet doesn't use this property : the generated svg is without this property.

Minimal example reproducing the issue

• [X] this example is as simple as possible
• [ ] this example does not rely on any third party code

var interactiveLayer = L.topoJson(epci2014TopoJson, {
        style: function (feature) {
            return {
                weight: 0.0,
                fillOpacity: 0.7,
                color: 'rgb(200,200,200)',
                fillColor: getColor(feature.properties.siren_epci || feature.properties.SIREN_EPCI)
            }
        },
        onEachFeature: function (feature, layer) {
            layer.on({
                mouseover: highlightFeature,
                mouseout: resetHighlight,
                click: zoomToFeature
            });

        }
    }).addTo(map);

    var justForDrawLayer=L.geoJson(departementsGeoJson, {
        style: function (feature) {
            return {
                pointerEvents : 'none',
                clickable:false,
                weight: 3,
                fillOpacity: 0.0,
                color: 'rgb(220,220,220)'
            }
        }
    }).addTo(map);

I have tried to put "clickable" to "false", no change.

Excuse me if my english is not enough right. Thank you.
