Unwanted modification of the Modelica code when the text is regenerated

[anonymous]

Example:

model A
  Real unwrapped;
  parameter Real phi = 1;
equation
  (,unwrapped) = Modelica.Electrical.Machines.SpacePhasors.Functions.ToPolar({Modelica.Math.cos(phi),Modelica.Math.sin(phi)});
end A;

Go to the text view in OpenModelica and check model (works fine). Now save the model. When you save it, an underscore is added:

model A
  Real unwrapped;
  parameter Real phi = 0;
equation
  (_,unwrapped) = Modelica.Electrical.Machines.SpacePhasors.Functions.ToPolar({Modelica.Math.cos(phi),Modelica.Math.sin(phi)});
end A;

Performing check model with this code generates the error "Variable _ not found in scope A".
