Presumably one can do this case too by: (1) clearing denominators, (2) working in a polynomial ring in all the variables, (3) and choosing a suitable term ordering on the indeterminantes, then (4) factoring in the bigger poly ring. Again, if somebody ones to make this work natively (without the user having to know any tricks), a patch would be welcome.
