Phantom JS没有捕获clipPath并从svg

Question

我有一个代码，用于在SVG下定义剪辑路径，然后通过URL引用组元素中的剪辑路径，但在使用Phantom JS截取屏幕截图时会忽略剪辑路径：

Phantom JS 1.9.8版和我使用的脚本

var webPage = require('webpage');
var page = webPage.create();
var system = require("system");
page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36';
page.viewportSize = { width: 1150, height: 900 };

page.open(system.args[1], function start(status) {
    window.setTimeout(function () {
        page.render(system.args[2], {format: 'png', quality: '80'});
        phantom.exit();
    }, 3000);
});

我无法在此发布完整的SVG代码，我刚刚发布了使用剪辑路径并做出反应的部分
