This means a forwarded message will*not* get its embedded reactions
processed. Well, forwarded messages will typically not have I-R-T set,
but if a message includes previous correspondence as an attached MIME
document.
Not 'typically'. A forwarded message is not a reply. So I'm not sure
how this is a problem.
In any event, if there is no In-reply-to: field, then this specification
is not relevant to that message.
However, In-reply-to in messages in the attached
correspondence will get their reactions processed if they are at the
correct relative level in the structure.
Let's see whether I understand, with an example meant to be more
interesting than the one in the specification:
From: me
To: you
Subject: I just got this message
---- Forwarded message
From: someone else
To: me
In-Reply-To: a previous message between us
Content-Disposition: reaction
U+1F997
The containing message isn't using MIME, to make the forwarded message
an attachment. I think it doesn't matter, for this example.
And the question is whether the contained message's reaction will be
processed as a reaction. The answer depends on how the MUA processes
such things.
In terms of semantics, the reaction is associated with that contained
(forwarded) message and not with the upper level (containing) message.
