PDF export fails after HTML blocks containing empty or named anchors are imported and inserted into a RadFlowDocument through ReplaceText.

HTML importer creates hyperlink field markers for <a name="...">. During block replacement, cloned FieldCharacter instances lose FieldInfo, leaving orphan field markers. PDF exporter later dereferences FieldInfo and throws a NullReferenceException.

Internally, the WebClient class is used to load external resources. This class is not supported in Blazor and WordsProcessing should provide a mechanism for loading the resource.

Removing/adding rows/columns inside a worksheet requires all the data after them to be translated according to the change. This operation is slow and affects editing performance.

Endless loop on PDF export when an empty string is assigned to text fields with no source /V and auto-sized default appearance (/DA with 0 Tf).

Workaround: Instead of an empty string (""), set the value to null. Or don't set it at all and leave it unmodified.

There are many instances of the internal Transition, State and ImageXObject classes.

Center alignment is not respected for list numbering.

Actual:

When two PDFs containing AcroForm fields are merged with PdfStreamWriter, the generated PDF contains page widget annotations whose parent field dictionaries are not correctly registered in the document-level /AcroForm/Fields tree.

The issue is reproducible by merging the same four-page form twice. The resulting PDF contains all widget annotations, but PDF viewers do not resolve the second form’s interactive fields correctly.

Calculation chain construction during import takes a lot of time for documents with formulas with large area references.

Calculation of array formulas with large area references takes a lot of time.

Missing table row content due to incorrect measurements after PDF export of a specific document.

InvalidDataException is thrown when importing an XLS document with malformed compressed picture data in the drawing layer.
