我正在使用带有RTL修复程序的 ExtJS 3.3.0，并且我对所有必需的类进行了覆盖以正确对齐字段。
不过，我一直遇到浮动表单的问题，我的字段标签有时会消失。我调查了这个问题，发现标签实际上并没有消失——它只是突然出现在左边（因此没有显示），没有明显的原因。
这是我的对话框的样子（第一次显示时）：
不幸的是，这是它第二次显示时的样子：
这是由 ExtJS 创建的窗口 HTML（注意：文档的 HTML 标记为dir="rtl"）：

注意：这只发生在 IE 中。
我曾多次阅读 IE 在RTL模式下存在浮动元素的问题，修复方法是将宽度设置为浮动元素的容器。
我已经在渲染后事件中这样做了，但无济于事：
newDateField.on('afterrender', function (field) {
var elem = field.getEl(),
p = elem.parent(),
formItem = elem.parent('.x-form-item');
p.setWidth(elem.getWidth());
formItem.setWidth(300);
}, this);
我也尝试过删除DOCTYPE并使用STRICT DOCTYPE. 也无济于事。
有什么建议么？
