When trying to show the RadRichTextBox' LineNumberingDialog, nothing is displayed. This happens when using the NoXaml Telerik dlls and themes other than Windows11. The dialog is shown only in the Windows11 theme.
To work this around, add the following two lines in the App.xaml resources.
<Application x:Class="WpfApp1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

</Application>
The issue reproduces when track changes is enabled and new text is entered. After waiting some time and pressing the Backspace on the keyboard in order to delete a character, nothing happens. You should press the Backspace a second time in order to make the deletion work. After that you can delete the content normally.
The waiting time before pressing the Backspace is usually until the next minute of the clock comes. For example, you can write something at 14:55 and wait until 14:56. Then, press Backspace.
If you check the Output pane of Visual Studio you will see the following assertion failure message printed:

NullReferenceException is thrown when the document gets updated after TableRow objects were removed with the Remove method of the parent Rows collection of the Table.
The table.Rows.Remove method is not properly removing some of the rows.

To work this around, use the DeleteTableRow method of the RadDocumentEditor.
RadDocumentEditor documentEditor = new RadDocumentEditor(document); documentEditor.DeleteTableRow(row);
It seems that the first time a Center TextAlignment is applied to the selection, its length is cached. Because of this, when the selection content (text) changes the length is not updated, thus the text doesn't align properly. It aligns accord to the initial length of the context. The content doesn't update also if the alignment is reset.
To work this around, avoid the FlowNoWrap layout mode and use only Flow.
When creating a hyperlink from selected text using the InsertHyperinkDialog, trailing spaces shouldn't be included in the hyperlink, as in MS Word.
Implement API for hiding built-in styles from StylesGallery. This should be useful, as currently all built-in styles are visible by default, and the only way to hide them is to include them in the document as set Primary to false.
The tooltip shown when hovering the styles in the ManageStylesDialog lists some unrelated values and should be revised.
Styles from RTF are incorectly copied to RRTB.
When you click for second time the caret locates in the correct position. I.e. there are needed 2 clicks before first line of paragraph which starts with bookmark to set the correct caret position. It also cause the problem of incorrect selection which will select the previous paragraph. This is because bookmarks essentially don't have position before them.
