为什么Infobox无法在Google Maps模式窗口内正确加载？

我有一个地图，上面有特定区域所有酒店的标记，当我单击每个标记时，会显示每个酒店的信息框。该地图将在模式窗口中打开。

当用户单击“查看更大的地图”按钮时，地图将显示在模式窗口中，默认情况下该特定酒店的信息框处于打开状态。但是，它没有正确加载的信息框，它似乎已损坏并且不在中央，当我单击标记时，它会正确显示它。

另外，当我关闭模式窗口并再次打开它时，地图不会完全渲染，因此我必须放大或缩小才能完全渲染它。任何想法？

我尝试过，google.maps.event.trigger(mapObject, "resize");但没有成功。
