I played around a bit (based on your code but in Java), and it looks like in
addition to creating your own appearance you also have to
a) remove the /Contents entry from the annotation:
comment.remove(PdfName.CONTENTS);
b) and add an /NM entry to the annotation, e.g.:
comment.put(PdfName.NM, new
PdfString("5e1f2eae-91ef-45bd-bc82-8e30be10a7bd"));
Probably you need not do a) if you create the appearance just like Adobe
Reader would do it (maybe you merely need to follow the recipe from section
12.7.3.3 "Variable Text" of the PDF specification ISO 32000-1)
Item b) is a bit surprising, though, as this annotation name entry is marked
as optional in the specification, cf. ibidem table 164 "Entries common to
all annotation dictionaries".
