The OnTextSelectionCompleted event of PdfViewer has as a parameter an instance of TextSelectionCompletedEventArgs. This parameter is a Dictionary[int, Dictionary[string, Rectangle]], with the inner dictionary supposed to map each selected string to its bounding Rectangle. However, instead the inner dictionary always contains only a single value, mapping all selected text to a single Rectangle. If multiple lines are selected, this single Rectangle may include text that is not selected.
