Whether or not this would break threading depends on the MUA or other
software doing the threading. For example, Mailman's pipermail
archiver prefers In-Reply-To: over References: for threading.

Multiple References: headers is a clear violation of RFCs 2822 and 5322
(RFC 822 is not clear on this point).

It would be helpful to those who may be using this broken Thunderbird
and perhaps others to know which Thunderbird version(s) has/have this
bug.
