The spacing between the letters is too big.

CheckBoxes defined on block level (i.e. wrapping a table cell) cannot be manually clicked at run-time.

Instead of moving the position after the content control, the caret goes on the last position in the control. This behavior affects keyboard input negatively, as users need to manually navigate to the right.

When content has a font-size applied in EM values and the UseDefaultStylesheetFontProperties property of HtmlFormatProvider is set to true, the imported content has pretty small values for font size.

When trying to export a document containing an ".ico" image to DOCX or RTF an exception is thrown.

When the Track Changes is activated, a Hyperlink is inserted to a text and we try to reject changes the rejection is not applied correctly.

The result:

After performance investigation related to feedback item http://feedback.telerik.com/Project/143/Feedback/Details/171108 , one bottleneck was identified as redundant calls to internal methods for getting parent of a document element.

Available in LIB Version 2018.2.820.

When the Track Changes is On and we try to change the style it applies the first time but the second try throws an exception and the style doesn't apply: System.ArgumentNullException: 'Value cannot be null. Parameter name: owner'.

1. Add new text "TEST".
2. Select the text and set a new style "Heading 2", then "Heading 1".
Observed: Heading 1 doesn`t appear.

When RadRichTextBox is bound to a data provider, there is a memory leak caused by a handler class related to the content controls functionality.

Whenever the focus is on RadRichTextBox, the keyboard is displayed with Uppercase by Default. After inputting 2-3 characters in uppercase, it changes to lowercase and then alternates between uppercase and lower per character.

When a content control check box updates it state at run-time, any local formatting is lost.

Workaround: Formatting defined in style definition is properly kept.

When the document is in Web layout mode (with RadDocument.LayoutMode = "Flow"), and contains multiple sections with comments inside them, the comments are visualized on unexpected places outside of the comments pane, or one over another, hiding other comments.

When the user inserts a table in right-to-left mode, there is no ability to resize its rows/columns. The Table Properties dialog or the Document Ruler still can be used to resize the rows/columns of the Table.

The table is not properly resized when using the left-most border. The table should be resized like in MS Word (see attached).

When a data provider is used, the designer does not show the RadRichTextBox content, that is shown with no problem at run time.

Workaround: The issue is with finding the format provider used by the data provider. This issue appears at design time only. The workaround is to manually set the format provider of the data provider:
        <telerik:HtmlDataProvider
            x:Name="htmlDataProvider"
            RichTextBox="{Binding ElementName=radRichTextBox, Mode=OneWay}"
            Html="&lt;h1&gt;Header3&lt;/h1&gt;">
            <telerik:HtmlDataProvider.FormatProvider>
                <telerik:HtmlFormatProvider />
            </telerik:HtmlDataProvider.FormatProvider>
        </telerik:HtmlDataProvider>

FloatingUIContainers are not cleared from the UI when they are deleted.

Workaround: Recreate UI using the following code:
this.radRichTextBox.ActiveEditorPresenter.RecreateUI();

When importing an image with а missing bitmap frame and trying to create a BitmapImage for it, the BitmapImage class throws an exception.
