The PDF standard allows two ways to configure Acro fields and relate them to inputs (widget annotations):

1. The field can be independent of the input widget. There can even be multiple inputs that point to the same field.
2. The field and the widget can be represented by the same object in the PDF file.

Adobe Acrobat supports both options. Telerik PdfProcessing supports only the first option, which is more commonly used. The PDF Viewer supports only the second option. If the PDF Viewer loads a file with the first configuration, the component saves new field values in such a way that they can't be retrieved by PdfProcessing. Moreover, if the PDF file is opened locally, it looks like the new values are there, but when you click on a field, the original value shows. The new value behaves like a placeholder rather than a real value.

To Reproduce

1. Open a file with Acro fields in the PDF Viewer with enabled form filling
2. Edit the fields and save the file.
3. Open the file with a desktop client like Adobe Acrobat Reader.
4. Click on a textbox.
5. Result - the old value shows. Instead, the new value should persist.
