Chrome 谷歌MapJavaScript API zoom issue with svg marker

我有一个简单的Map与SVG文件作为标记图标。当Map加载没有问题，但如果我试图放大或缩小，图像变大，是切断。此行为随浏览器的不同而变化：

谷歌Chrome启动正常，但如果你试图缩放它揭示了问题。
Safari运行良好
Firefox没有显示

我认为这是一个svg相关的问题，但我找不到bug在哪里。我用这段代码创建了一个jsfiddle

var mapOptions = {
    zoom: 5,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    center: new google.maps.LatLng(52.373743,4.893114)
};

map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

    var icon = {
    url: "http://filippopoderini.com/marker-07.svg",
    anchor: new google.maps.Point(23,60),
    scaledSize: new google.maps.Size(46,60)
}

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(52.373743, 4.893114),
    map: map,
    draggable: false,
    icon: icon,
});

这是svg代码

一旦Map缩放发生变化，请尝试 * 显式 * 更新标记图标，如下所示：

google.maps.event.addListener(map, 'zoom_changed', function() {
  marker.setIcon(icon);
});

修改jsFiddle

function initMap() {

  var map;
  var polyLine;
  var polyOptions;



  var mapOptions = {
    zoom: 6,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    center: new google.maps.LatLng(52.373743, 4.893114)
  };

  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

  var icon = {
    url: "http://filippopoderini.com/marker-07.svg",
    //anchor: new google.maps.Point(23, 60),
    //scaledSize: new google.maps.Size(46, 60),
    size: new google.maps.Size(46, 60)
  }

  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(52.373743, 4.893114),
    map: map,
    draggable: false,
    icon: icon,
  });

  google.maps.event.addListener(map, 'zoom_changed', function() {
      marker.setIcon(icon);
  });  

}


google.maps.event.addDomListener(window, 'load', initMap);

#map-canvas { 
    height: 400px; 
}

<script src="https://maps.google.com/maps/api/js"></script>
<div id="map-canvas"></div>

P.S.已在Chrome v51中验证

我遇到了同样的问题，经过一些调试后解决了它。我错过了SVG本身的宽度/高度。这需要与viewBox的宽度/高度相同。然后SVG在放大/缩小时正确调整了大小。
