Yep.  This bug is present in all versions of Sugar.

Actually, I now believe that your characterization is right.
SharedTextDemo does _not_ handle this situation correctly, because Sugar
makes it basically impossible.  I was thinking of the situation in which A
initiates, B joins, A leaves, B edits and leaves, A resumes and edits, and
then B joins by resuming.

Both of these bugs are worth fixing, especially now that there are
activities that can really make use of re-joining.
