Temporary workaround for Leaflet 0.7.5 disappearing tiles on iOS

patch.js

L.Map.prototype._onZoomTransitionEnd = function () {
    if (!this._animatingZoom) { return; }

    this._animatingZoom = false;

    L.DomUtil.removeClass(this._mapPane, 'leaflet-zoom-anim');

    L.Util.requestAnimFrame(function () {
        this._resetView(this._animateToCenter, this._animateToZoom, true, true);

        if (L.Draggable) {
            L.Draggable._disabled = false;
        }
    }, this);
};
