(DIPs) is a unit type used in RadWordsProcessing when setting the FontSize of a Run. If you load a document with font size in WordPad set to 20 points and load it to RadFlowDocument, its value is converted by using the following method. If the RTF content stored from WordPad is saved to HTML format with WordPad, the font size is preserved with the same unit: style='font-size:20.0pt;'. We should add the option to control the font size unit when exporting to HTML format.

Generate a document with the following approach: https://docs.telerik.com/devtools/document-processing/knowledge-base/populate-table-data-mail-merge

Before calling MailMerge, add two document variables with the editor: https://docs.telerik.com/devtools/document-processing/libraries/radwordsprocessing/concepts/fields/document-variables 

 Replace cannot match whole word with special characters (e.g. "#", "@", "&") at the start/end.

Workaround (RegEx):

editor.ReplaceText(new Regex($"(?<=\\s|^|[\\c_]){placeholder}(?=\\s|$|[\\c_])"),"new content");

Add support for Picture Styles.

InvalidOperationException when cloning a document containing fields spanning multiple paragraphs.

Workaround: instead of new paragraphs, use line breaks (Shift+Enter).

The default vertical alignment value of table data (<td>) is incorrect.

Current: "vertical-align: top;"

Expected: "vertical-align: middle;"

Workaround: Explicitly set the "vertical-align: middle;" of <td> elements.

XmlException is thrown when importing documents containing DAT files.

    using (ZipArchive archive = ZipArchive.Update(ms, null))
    {
        var zipEntries = archive.Entries;

        // Skip glossary on importfor (int i = zipEntries.Count() - 1; i >= 0; i--)
        {
            var entry = zipEntries.ElementAt(i);
            string entryName = entry.FullName;
