It turns out HK strips the angle brackets `< >` when internally storing the
message-id and in-reply-to header. It adds them back to Message-ID when
exporting but doesn't add it back to In-Reply-To. I have opened [1] for the
issue.

Because of that, when the header is folded, an additional whitespace is added
to the start resulting in broken threads.
