The field displaying the barcode has a PMD entry which is used to generate a barcode depending on the content present in its V entry.
If I change the name PMD then the barcode is no more generated.
I don't find anything in the pdf specifications about that, so it's likely something we won't support.
In Chrome the barcode isn't updated and in Edge the barcode isn't displayed at all which is probably the best option in order to avoid any confusion.
