User(s) can reproduce this bug

In ASP.NET MVC 3 with ASPX

Html.DropDownListFor does not select the correct item from the drop down when used in an Editor Template.

It however works as expected when used 'normally' when not embedded in an Editor Template.

Visual Studio 2010

A repro of the problem can be downloaded here:
http://filegooi.co.za/get2/162a5792df996487577668c4d213554a/MvcDropdownBug.zip

Steps to reproduce:
1. Create a view model containing a complex type (e.g. Address) to be used in an Editor Template. This model should also contain the list to select from. (e.g. Country List)
2. Create an Editor Template that makes use of the Html.DropDownListFor method. (e.g. Country list for an address)
3. Create a view (.ASPX) that points to the Editor Template in step 2. (i.e. Html.EditorFor)
4. In the Controller update the view model to indicate which item should be selected. (e.g. model.CountryCode = "ZAR")
5. Pass in the view model to the view. The incorrect behaviour should be apparent here, as the wrong item is selected (it seems to default to first item in the list).

Side note:
Repeating the above without using and Editor Template works as expected.

The model for the country code is set to ZAR but it incorrectly set the value to USA.

Setting the model to ZAR should selected ZAR in the drop down.
