PDFDoc::sign paramter borderWidth has no effect

In poppler/PDFDoc.cc the method PDFDoc::sign takes a parameter double borderWidth, which is used to set the signature annotation widget's border:

std::unique_ptr<AnnotBorder> border(new AnnotBorderArray());
border->setWidth(borderWidth);
signatureAnnot->setBorder(std::move(border));

However, the call to signatureAnnot->generateFieldAppearance() happens before the quoted lines and therefore the quoted lines have no effect.
