The Thalmor Dossier says explicitly that they must be as hands off as possible in the Civil War. The only aim of propping up the Stormcloaks is to keep the war going on, not because their victory would be more favourable. The Dossier is completely neutral in regards to which outcome would be better for the Thalmor. Whether or not Stormcloak victory would be the best outcome objectively, that's being discussed in another thread!
