It is an option for the SIP dissector, so you must select the SIP layer in the
packet detail view instead of the packet in the packet list (which would give
you the SIP preferences).

True, because delayed tracking is disabled by default.

Ok, I'll close the bug since the original issue is fixed (with a workaround).
Normally requests and 2xx responses create a new offer (with the workaround it
will directly create a media session without waiting for the answer), but for
provisional 1xx responses, by coincidence the next invocation of dissect_sdp
directly creates a media session.
(This mechanism in dissect_sdp is supposedly used for protocols like RTSP which
do not use the Offer/Answer model, see also bug 5208 for RTSP problems.)
