DropDownListFor does not select value if in for loop

Not sure if this is new to mv4 or if it exists in prior version. But the DropDownListFor includes an additional parameter for the SelectList Constructor.

SelectList(IEnumerable, String, String, Object)

For example:

Html.DropDownListFor( x => x.Countries[ i ], New SelectList(Model.CountryList,"ID","Description",Model.Countries[i]))

Where ID is the Country ID in the CountryList object and Description is the Country Name.
