When copying the formatting using span to span selection, any formatting applied with a character style is lost. 

When selection is applied quick after format painter is clicked formatting is not applied.

The Outline view shows the content of a document as bulleted points. It enables the user to easily move whole paragraphs within the document or to create headings.

Allow the customers to change the properties defined in the default stylesheet. They need to change properties like font size, font family, border-spacing, line-spacing, as in RadRichTextBox they might be different from the ones used by the browsers.

Loading large documents freezes the UI. Instead, the document could be imported and measured asynchronously in a background thread, and some progress indicator shown to the user.

Note: Image sources should be frozen when the document is loaded in a background thread.

Workaround: Following the steps:

- Import the document in a background thread using the specific format provider. 

- Freeze all images in the document using the methods in the attached file.

- Set the document to RadRichTextBox in the main thread using a dispatcher:

this.Dispatcher.Invoke(new Action(() =>
{
    this.radRichTextBox.Document = document;
}));

Implement an option for the customers to split a document into two views, allowing them to edit and view different parts of the document at the same time.

When a hyperlink (and only the hyperlink) is selected, and the user types over the selection, the hyperlink is deleted, and text with locally set blue fore color and blue underline is inserted. 

Instead, the hyperlink should be preserved, and just its link text should be modified.

The custom list styles from a document exported by RadRichTextBox's HtmlFormatProvider are not imported.

Annotation Ranges where SkipPositionBefore is set to false on the AnnotationRangeEnd cause cursor jumps when deleting content to the right of the Annotation Range.

Steps to reproduce:
1. Open a job with Annotation Ranges where SkipPositionBefore is set to false on the AnnotationRangeEnd (I used the Document Protection sample in the demo app)
2. Move your cursor to the end of the range.
3. Hit the delete key
Expected: The cursor remains at the end of the AnnotationRange and content to the right is deleted.
Actual: Content to the right is deleted but eventually the cursor will jump to the right by one position and end up outside the Annotation Range.

When there is a hyperlink enclosed in another annotation (e.g comment, bookmark, read-only range), and the user moves the caret position just before or just after the hyperlink, and starts typing there, the text is inserted with the style of the hyperlink (by default, blue with blue underline). Instead, the text should be inserted without such style.

The TxtFormatProvider always imports the document with UTF8 encoding. It will be great if users could change this setting in order to import document with different encodings.

Deleting table right after merged fields are updated causes StackOverflowException.

The caret gets a wrong size when positioned on annotation start/end.

Currently, RadRichTextBox only imports from HTML documents tables with spacing between cells, but it does not export tables with such style. It seems like the border-collapse: collapse value defined in the Table Normal style overrides the border-spacing value, which is applied to the cells.
As a workaround, the document styles can be omitted from the exported HTML and the styling can be exported inline be changing the ExportSettings of HtmlFormatProvider:
provider.ExportSettings.StylesExportMode = StylesExportMode.Inline;
provider.ExportSettings.StyleRepositoryExportMode = StyleRepositoryExportMode.DontExportStyles;

Using Microsoft Pinyin IME for typing in the RichTextBox causes FatalExecutionEngineError exception. 

Currently there are three places in the UI which contain a list of font sizes which could be applied to the content, and all of them could be customized separately:
- RadRichTextBoxRibbonUI - could be customized by directly editing the content of the ribbon in the XAML file.

- FontPropertiesDialog - could be customized by replacing the whole dialog (as SDK is available: https://github.com/telerik/xaml-sdk/tree/master/RichTextBox/CustomFontPropertiesDialog ), or a little hacky approach using the FindName method:

((ListBox)((Control)this.radRichTextBox.FontPropertiesDialog).FindName("fontSizeListBox")).ItemsSource = new List<double> { 10, 14, 16, 18, 20 };

- SelectionMiniToolBar - could be customized by changing the template of SelectionMiniToolBar

Provide API which allows customization at a single place. This API could be similar to (or even extension of) the already available Telerik.Windows.Document.Layout.FontManager class.

Having a table with specified RowSpan and further exported to PDF does not draw the border. This is due to export optimization caused by the fact whether there is or is not a CellSpacing specified.

Workaround: Set really small CellSpacing for the table.

When document with TOC  field is exported to PDF, the hyperlinks in the TOC field are exported with blue fore color and blue underline (with the default hyperlink styling). Instead, they should be exported with the fore color visible in the document.

Workaround: Clear the hyperlink style from the spans inside the TOC:

var firstTocRange = this.radRichTextBox.Document.EnumerateChildrenOfType<FieldRangeStart>().Where(frs => frs.Field is TableOfContentsField).First();
this.radRichTextBox.Document.Selection.SelectAnnotationRange(firstTocRange);
foreach (var spanLayoutBox in this.radRichTextBox.Document.Selection.GetSelectedBoxes<SpanLayoutBox>())
{
	spanLayoutBox.AssociatedSpan.Style = null;
}

Inserting image inline from stream changes its size dramatically.

Run the following code to reproduce:

            RadDocument document = new RadDocument();
            RadDocumentEditor editor = new RadDocumentEditor(document);
            //editor.Insert("some text");
            using (FileStream stream = File.OpenRead(@"C:\Temp\picture.jpg"))
            {
                editor.InsertImage(stream, ".png");
            }
            File.WriteAllBytes($@"d:\Temp\test\test_doc.pdf", new PdfFormatProvider().Export(document));

The issue is observable after 2017.2.614.
