Circle isn't appearing in IE11, but works in every other browser. Trying to implement a radius search feature.

Any ideas why this might be occurring? I've seen other fiddles, and they seem to implement Circle properly. I think the drawing of the circle is registered, since it shows up in my elements, but I can't actually see the circle nor does it get highlighted by the Inspect Element highlighter.

addCircle = (lat, lng, radius, map) => {
        if (this.circle) {
            map.removeLayer(this.circle);
        }
        this.circle = L.circle([lat, lng], radius, {className: 'mapSearchCircle'});
        this.circle.addTo(map);
    };

    doneDrawingCircle = () => {
        this.drawing = false;
        this.setState({alert: true});
        this.circle.on('click', this.circleClicked.bind(this));
    };

I don't believe there's nothing going on with styles or anything.
