The issue is hard to reproduce as it seems to depend on a specific combination between a resolution and text scaling.

When importing a XAML document that contains a Content control with PrefixMappings to its TextProperties` DataBinding an exception is thrown: 'Telerik.Windows.Documents.Model.StructuredDocumentTags.DataBinding.PrefixMappings' threw an exception.'

Currently, the uncommitted text is always underlined with a dotted line. Provide an option for disabling that behavior.

When committing the text, the automatic underline should be removed from the content. However, it is preserved for all spans inserted with the IME.

The default combo box item is restored when on exports content controls to xaml and then imports back

Setting "Content control cannot be deleted" for a Plain Text content control breaks the editing rule and the user cannot edit the Plain Text control.

User is able to type in a content control even though its editing is not allowed by setting the "Content control cannot be edited" option.

RIchTextBox: Changing the current value of ComboBox/DropDownList/DatePicker/CheckBox content control causes two items to appear in the undo stack - Delete and Insert.

Unable to place the cursor before a single vertical line character at the start of the line (ex. "I", "i", "l").

The cursor jumps to the next line sometimes when clicked at the end of the line.

The HighlightColor of spaces at the end of the line is not correct when the FlowNoWrap mode is used.

CopyPropertiesFromOverride() method of InlineUIContainer is called more than once for every Copy/Paste command.

The error is thrown while measuring a nested table and one of its rows is separated on different pages. 

The document can be properly visualized in MS Word and RadRichTextBox but upon opening it with WordPad, the image is not visible. Trying to create a FlowDocument object from it leads to an exception (System.Runtime.InteropServices.ExternalException: 'A generic error occurred in GDI+.').

When in Header/Footer mode trying to insert a content control causes it to be added inside the main document.

When importing a document with a content control present inside the header/footer, only the content remains and the control itself gets stripped.

When the definition of font-weight contains a CSS variable as a value for the property, NullReferenceException is thrown while importing the content.

When the definition of margin-[left/right] contains a CSS function as a value for the property, NullReferenceException is thrown while importing the content.

The paragraph is not correctly copied and carries empty inlines that cause the exception.

Workaround: Add some content to the inlines of the copied paragraph:

RichTextBox: Exception when loading a table with a specific layout in R2 2022

This works with R1 2022 SP1
