Modelica.Fluid.Examples.TraceSubstances.RoomCO2WithControls is problematic because of chattering #4312

As reported in #4305, Modelica.Fluid.Examples.TraceSubstances.RoomCO2WithControls is problematic: Dymola 2024x fails with it and so does OpenModelica. Apparently there are some reasons to generate chattering.

This should be investigated before the 4.1.0 release.
