SVG 蒙版剪辑在 Firefox 中不起作用

Question

我一直在尝试通过使用 SVG 蒙版来实现这种滚动效果。它在 Chrome 中运行良好，但在 Firefox 中似乎不起作用。我创建了一个 dabblet 来显示我得到的行为：http://dabblet.com/gist/83bf9a8708193634892e

创建剪贴蒙版的正确方法因浏览器而异（更多信息请参见here）。当然，对于 Chrome 和 Firefox，我已经使用了两种指定的方法。

SVG 文件如下所示：

尝试在 Firefox 上实现它时我做错了什么？ 像往常一样，非常感谢任何形式的提示或帮助！

掩码需要设置填充颜色，例如

#wrapper {
	width: 600px;
	height: 600px;
	background: black;
}

#wrapper .container {
	width: 100%;
	height: 100%;
	overflow-x: hidden;
	overflow-y: scroll;
            mask: url(#mask);
}

#wrapper .container .inner1,
#wrapper .container .inner2,
#wrapper .container .inner3 {
	width: 100%;
	height: 100%;
}

#wrapper .container .inner1 {
	background: red;
}

#wrapper .container .inner2 {
	background: green;
}

#wrapper .container .inner3 {
	background: blue;
}

<div id="wrapper">
	<div class="container">
		<div class="inner1"></div>
		<div class="inner2"></div>
		<div class="inner3"></div>
	</div>
</div>
