My crystal ball says the window has a third seal, namely in the sash on the room side.

The crystal ball is correct. But what is it now? Pressure equalization or (unwanted) forced ventilation?

If no gaps/holes/breaks/... or rebate vents(?) can "interrupt" the middle seal and the inner stop seal, it can only be a pressure equalization that has nothing to do with ventilation. Notes: Quite a few laypeople/"experts" do not recognize "rebate vents"... this is especially the case with the new models of a manufacturer. Unfortunately, rebate vents are also often installed incorrectly (= not according to manufacturer instructions)... for example, there are too many large seal cutouts or the opposite...
