ExtJS: DatePicker width issue

The issue with DatePicker control width appears in Safari starting version 4.0.4 if Doctype declaration for the page is missing.

Here is a quick fix for it that should be included in the style section after ExtJs stylesheet:

.ext-safari .x-date-picker 
{
    width: 185px;
}

As reported on ExtJs forum this problem is fixed in 3.1.
