When using the following code to copy annotated pages, iText 7.1.0 duplicates the /Popup annotation, the only difference between the "original" and the duplicate being that one has a /Parent entry and the other doesn't.
Unfortunately, the one without the missing /Parent is registered in the /Annots list of the /Page dictionary. How can I make iText not duplicate the annotations or at least register the one with the /Parent entry? Any explanation for the odd behavior?

for (int i = 1; i <= inputDoc.getNumberOfPages(); i++) {
inputDoc.copyPagesTo(i, i, outputDoc);
}
inputDoc.close();
outputDoc.close();
}
