我有一个CSSbackground-image设置在具有流体高度和宽度的元素上。它是一个 SVG，预期的行为是让它向任何必要的方向拉伸以覆盖整个元素的区域。在 Chrome、Safari，甚至是糟糕的 Internet Explorer 9 中，缩放可以按照我想要的方式进行：
但在 Firefox（桌面版和移动版）中，输出更像是这样：
经过一番研究后，Firefox 似乎比其他浏览器对 SVG 渲染更加严格，因为它严格遵守最新版本的规范。 （Opera Mini 也无法渲染此背景图像（启用时），因为它不会缩放图像down，并且考虑到 Presto 引擎一贯以夏季雷暴般的认真态度来处理规格问题，因此它可能会采用与 Firefox 相同的更新方法。）
您可以看到我正在处理的实时页面http://ti.gt/ http://ti.gt/。我还提供了我正在使用的代码如下：

我尝试了多种策略来让 Firefox 接受我的要求，但到目前为止还没有一种成功。我看过了本文档正是关于这个主题的 https://developer.mozilla.org/en-US/docs/Web/CSS/Scaling_of_SVG_backgrounds，但我无法从中提取任何建议。
