It is supported, but the the TeX method of Dom::DistributedPolynomial
had a bug. Iff the polynomial consisted of exactly one term with
degree > 0, it was printed twice as s above. I have fixed the bug
in the development version of MuPAD, but the fix come too late for
version 3.1.
If you are interested, I can send you a patch via email.
