Sometimes problem with 'orphaned' spaces

Sometimes the HtmlFromXamlConverter misses whitespace because it is not in a <Run> or similar tag. I hacked a fix by inserting the following code at line 46 of HtmlFromXamlConverter.cs:

            string regex = @"\>[ ]{1,}\<(?!\/)";
            Match m = Regex.Match(xamlString, regex);
            while (m != null && m.Success)
            {
                xamlString =
                      xamlString.Substring(0, m.Index + 1)
                    + "<Run xml:space='preserve'>" + new String(' ', m.Length - 2) + "</Run>"
                    + xamlString.Substring(m.Index + m.Length - 1, xamlString.Length - (m.Index + m.Length - 1));
                m = Regex.Match(xamlString, regex);
            }

Open HtmlFromXamlConverter.cs at line 46 and reproduce conversion of XAML containing whitespace outside a Run or similar tag. Review the reported regex and replacement behavior, then verify that the converted HTML preserves those spaces without changing other XAML content.
