RichTextBox: The layout updates stop as a result a handled NullReferenceException after pasting a table with an empty first cell as the first element in the document
There is a NullReferenceException thrown while trying to compare positions for restoring them after pasting the document. The exception is handled but after it is thrown, the layout stops updating.

Workaround: Ensure the document is not empty before pasting content inside:
private void RadRichTextBox_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
    if (e.Command is PasteCommand && this.radRichTextBox.Document.IsEmpty)
        this.radRichTextBox.Insert(" ");
