Impossible to set initial spees in rad/s from GUI

[massimo ceraolo]

Consider the follwing model:

model speed
  Modelica.Mechanics.Rotational.Components.Inertia ICE(J = 0.73, w(displayUnit = "rpm", fixed = true, start = 17.48)) annotation(
    Placement(visible = true, transformation(extent = {{-12, -8}, {8, 12}}, rotation = 0)));
equation

annotation(
    Diagram(coordinateSystem(extent = {{-100, -80}, {100, 80}})),
    uses(Modelica(version = "3.2.3")));
end speed;

From the gui it seems possible to set the initial speed in rad/s, but indeed it is impossible.
