Handle import of documents with self-referring styles.

As a workaround, you can go through the RTF document structure of a single file and utilize Regex to resolve the self-referring styles like this:

string rtf = File.ReadAllText("inputFile.rtf");
rtf = FixSelfReferringStyles(rtf);

Telerik.Windows.Documents.Flow.FormatProviders.Rtf.RtfFormatProvider provider = new Telerik.Windows.Documents.Flow.FormatProviders.Rtf.RtfFormatProvider(); 

 var document = provider.Import(rtf);

...

private static string FixSelfReferringStyles(string rtf)
{
    string regexString = @"{\\s([0-9]+)[^}]*\\slink([0-9]+)";

    var matches = Regex.Matches(rtf, regexString);
    foreach (Match match in matches)
    {
        if (match.Groups[1].Value == match.Groups[2].Value)
        {
            var oldValue = match.Groups[0].Value;
            var newValue = oldValue.Replace(@" \slink" + match.Groups[1].Value, string.Empty);
            rtf = rtf.Replace(oldValue, newValue);
        }
    }

    return rtf;
}

Workaround:

var fieldInfo = editor.InsertField("TOC");
fieldInfo.UpdateField();
fieldInfo.IsDirty = true;

Merging (with RadFlowDocumentEditor's InsertDocument method) documents containing lists sometimes doesn't properly resolve the ListId properties.

Workaround: Removing the list with bullets resolves the issue as there is only one ListId to pick from:

document.Lists.Remove(1); 

When there is a document (e.g. docx) with hanging indent in a list and this document is imported and then exported to HTML, the text overlaps the bullet as shown in the screenshot.

Importing a document containing a hyperlink (<a>) tag without content extends it over the trailing elements.

For example, importing this HTML:

<a></a>
<p>First paragraph</p>
<p>Second paragraph</p>
<p>Third paragraph</p>

Generates:

Instead of this:

Indent of BodyTextIndent style applied to a paragraph is not respected on export.

Workaround: Remove the applied style.

var p = run.Paragraph;
p.Properties.StyleId = string.Empty;

List's top and bottom margins are not correctly exported.

Workaround: Apply TelerikNormal style to the 'ol' element.

Import/Export of specific documents sets style background color to black.

Workaround: do the following conversion of the document with the Document Processing libraries: originalRtf -> exportedDocx, exportedDocx -> finalRtf. After that processing, the finalRTF file will no longer reproduce the issue when exported.
