String not displaying properly in HTML5 Viewer

I have a form in a workflow that populates the "Parcel Description" portion of the form with attribute values from the parcels layer at runtime. Here is the string:

form.Find(Of GroupBoxFormItem)("GroupBox2").Description = String.Format("Land District: {1}{0}Land Lot: {2}{0}Subdivision: {3}{0}TIN: {4}", Environment.NewLine, landDistricts, landLots, subdivisions, TIN)

The Silverlight Viewer displays the string correctly:

/customer/servlet/servlet.FileDownload?file=00P6000000elzFNEAY

The HTML Viewer does not. It displays the <br/> tag where each Environment.NewLine is defined. It looks like this:

Land District: 14 <br />Land Lot: 0131 <br />Subdivision: River Falls <br />TIN: 14N17A053

Does anyone know how I can use HTMLString in my workflow to cause the string to display properly in my HTML5 Viewer?
