The ChangeListStyleCommand has an event named ListStyleChangedChanged  which is never raised.

Trying to delete table cell formatting symbol, when track changes are on, will result in marking the text in the cell as deleted.
MS Word does not respect such delete action.

Hyperlink tooltip is not changed when the HyperlinkNavigationMode property of RadRichTextBox is changed.

Workaround: Invoke radRichTextBox.ActiveEditorPresenter.RecreateUI() method just after the property value change:
this.radRichTextBox.HyperlinkNavigationMode = HyperlinkNavigationMode.Click;
this.radRichTextBox.ActiveEditorPresenter.RecreateUI();

Steps to reproduce:
1. Insert a hyperlink in RTB.
2. On button click change the HyperlinkNavigationMode.

Observe: The tooltip is not changed from Click to ... Ctrl + Click to .. and vise versa.

When the main container of a window is ScrollViewer, the caret is not kept in the view while users move it with the arrow keys.

TabStopsProperties dialog is non-modal dialog, but it should be modal.

If there are two words with two spaces between them, and between the spaces there is annotation with SkipPositionBefore = false (e.g. track changes revision annotation or comment), and current editing style is changed on the position between the spaces (i.e. Toggle Bold, for example, without selection present) the first word formatting is affected (e.g. it becomes bold).

Steps to reproduce:
Variant 1:
- Insert two words with a single space between them (e.g. "text telerik")
- Turn Track Changes On
- Insert a space after the single space between the two words. (i.e. right before 'telerik')
- Toggle Bold
Observe: "text" gets bold.
Expected: "text" doesn't get bold, just current editing style is changed.

Variant 2:
- Insert two words with a two spaces between them (e.g. "text  telerik")
- Select the second space and the second word, and insert comment.
- Put the caret between the spaces.
- Toggle Bold
Observe: "text" gets bold.
Expected: "text" doesn't get bold, just current editing style is changed.

When floating image is added to empty table cell, it is positioned in a way that overlaps the table border. 

Clicking on floating Image when the caret position is not in the viewport, changes the viewport and starts image dragging. Instead, the image should just be selected.

Steps to reproduce:
1. Start with empty document
2. Insert image, make it floating (right-click on it, select Text Wrapping -> In Front Of Text)
3. Drag the image near the bottom of the document.
4. Scroll and, if needed, zoom to such a factor, so that the first paragraph is outside of the view port.
5. Select the image (keep in mind that the image shouldn't be selected - the position should be at some of the previous paragraphs)
Observe: The image dragging adorner is visible and the viewport is changed.
Expected: The behavior shall be the same as MS Word - the viewport shouldn't be changed, and the image should just be selected

When inserting text (document fragment) next to a correctly spelled word they get both underlined as incorrect.

Currently when the text contains consecutive non-space symbols like "~!@#$%^&*()_+=-`[]{};:'"/\|., ", each character is detected as a separate word. Instead, they should be considered one word, including all the subsequent space characters.

The following functionalities should respect this grouping:
- Caret navigation by words (CTRL + left/right arrow), MoveCaret UI command and the corresponding DocumentPosition methods.
- Selecting word by double clicking.

'Decrement paragraph left indent' command can set negative left indent which makes bullets/numbering of a list clipped. Instead, it shouldn't be executed if the bullets/numbering would become invisible.

Workaround: Cancel the command in CommandExecuting event:

            this.radRichTextBox.CommandExecuting += (sender, e) =>
            {
                if (e.Command == this.radRichTextBox.Commands.DecrementParagraphLeftIndentCommand)
                {
                    if (this.radRichTextBox.Document.Selection.GetSelectedParagraphs().Any(p => p.IsInList && p.LeftIndent <= 24))
                    {
                        e.Cancel = true;
                    }
                }
            };

The spacing between the letters is too big.

The built-in Hyperlink style is not applied to hyperlinks imported from HTML (<a> tag). As a result, the hyperlinks in the document do not have the blue underline.

Workaround: Subscribe for the SetupDocument event of the HtmlDataProvider and set the hyperlinks' style manually.
private void HtmlDataProvider_SetupDocument(object sender, Telerik.Windows.Documents.FormatProviders.SetupDocumentEventArgs e)
{
    StyleDefinition hyperLinkStyle = e.Document.StyleRepository[RadDocumentDefaultStyles.HyperlinkStyleName];
    hyperLinkStyle.SpanProperties.ForeColor = Colors.Green;//Color.FromRgb(0xff, 0x7a, 0xcc);
    var hyperlinks = e.Document.EnumerateChildrenOfType<HyperlinkRangeStart>();

    RadDocumentEditor editor = new RadDocumentEditor(e.Document);
    editor.Document.History.IsEnabled = false;

    foreach (HyperlinkRangeStart hyperlink in hyperlinks)
    {
        e.Document.Selection.SelectAnnotationRange(hyperlink);
        editor.ChangeStyleName(RadDocumentDefaultStyles.HyperlinkStyleName);
    }
    e.Document.Selection.Clear();

    editor.Document.History.IsEnabled = true;
}

When RadRichTextBox.DocumentInheritsDefaultStyleSettings is set to true, lists in the document are exported to HTML with Verdana font, instead of with the font applied in the UI.

Workaround: Use modification of the document default styles ("Normal") instead of setting DocumentInheritsDefaultStyleSettings  to true, e.g.:
this.radRichTextBox.Document.StyleRepository["Normal"].SpanProperties.FontFamily = new FontFamily("Segoe UI");

The TableCellProperty.Padding property of the "TableNormal" StyleDefinition doesn't take effect in the UI. The same is valid for the TableProperties.CellPadding property.

To work this around, you can manually set the Padding property of all TableCell elements in the RadDocument.

 var cells = radDocument.EnumerateChildrenOfType<Telerik.Windows.Documents.Model.TableCell>();
 foreach (var cell in cells)
 {
     cell.Padding = new Padding(10);
 }

When RadRichTextBox for WPF is hosted in a WinForms application (through ElementHost), typing with Japanese IME duplicates the typed letters, which makes the control unusable with the default behavior.

Possible workaround: Create custom caret. There are some suggestions in this forum thread: https://www.telerik.com/forums/richtextbox-doesn't-support-japanese-ime-when-hosted-in-winforms

Can be reproduced in the demo:

• Open the default document in the radrichtextbox demo
• Activate change tracking (button "Track Changes")
• Make a modification to the document (delete a paragraph)
• Hover your mouse over the delete text: the date in the revision info. has always ":00" for the seconds

In our processes, it is very important to know if a change happened before or after another action. If all the revisions have zero seconds, it's impossible to determine the order of the changes when they happened in the same minute.

This is not a new bug introduce in SP2: it was there in SP1.
