Yes, it's not documented. There is only a comment in the source code:

                            # ';' is a comment delimiter only if it
                            # a spacing character

I think it's either a bug in the code or in the documentation.

If you follow the documentation, comments are ONLY allowed to start a
The actual implementation discards any text following a <space>;

RFC822 uses ";" to include comments in the syntax rules, not for
comments in the actual message headers (parenthesis are used there).
