bug: selecting newly created option in dropdown causes javascript error in IE

> If an interaction with a form results in a new option being added to a
> dropdown, and in the same action this new option becomes selected I get
> a javascript error.
>
> The problem occurs on this line:
>     option.selected = xformsArrayContains(selectedValues, option.value);
>
> This seems to be some obscure problem with IE where if a option is added
> to the DOM then quickly set to selected an error occurs (see
> http://ianso.blogspot.com/2005/10/another-stupid-ie-bug-selectedindex-on.html,
> http://www.thescripts.com/forum/thread150463.html).
>
> Workaround for IE is to use
>     option.setAttribute('selected',xformsArrayContains(selectedValues,
> option.value));
>
> but this won't work for Firefox...
>
> Attached is example demonstrating the problem (which only occurs in IE)
> - click the add version link at the bottom to see the error.
