溢出：Windows 7上的Firefox26隐藏的错误

Question

Firefox中的一个奇怪的错误只发生在非常特定的环境中，即Windows 7 SP1计算机上的Firefox版本26（至少在两台不同的计算机上确认）。在Windows 8上的Firefox 26上不会发生此错误，在Windows 7上的Firefox 25.x上也不会发生此错误。

从下面的屏幕截图中可以看到，实际的错误是树视图控件中的文本突破了容器，该容器上有一个溢出：hidden。

Windows 7上的Firefox 26上的图像：

Windows 8上的Firefox 26上的图像：

我尝试了什么

• 使用firebug与溢出设置混淆，没有效果。
• 对结构进行微小改动，没有效果。

树视图是一个Kendo UI树视图，该网站通常使用Bootstrap 2.x作为基本CSS。没有其他浏览器显示此问题。

编辑：

jsFiddle available here确保将结果窗口扩展到足以使树视图可见（它隐藏在较小的屏幕上）。 html可能有点草率，因为我试图切掉任何不必要的东西，但仍然不得不留下大量的毛茸茸以避免删除问题本身。

也报告为Firefox bug.

Answer 1

这就是我在屏幕上看起来的样子 - 据我所知，这是正确的。

我的firefox是（德语）26.0：

我正在运行Windows 7 SP 1：

很抱歉图片垃圾邮件，但我认为这是必要的，以确保版本中没有误解。

您是否检查/禁用了插件？
