Conditional connection is not displayed

[FWuellhorst]

Description

Conditional connections are not showing.

Steps to Reproduce

Create this model

model ConnectionNotShowing
  parameter Boolean useConst=true;
  Modelica.Blocks.Sources.Constant const annotation(
    Placement(visible = true, transformation(origin = {-10, 10}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  Modelica.Blocks.Interfaces.RealOutput y annotation(
    Placement(visible = true, transformation(origin = {110, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0), iconTransformation(origin = {72, 14}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
equation
  if useConst then
    connect(const.y, y) annotation(
    Line(points = {{2, 10}, {78, 10}, {78, 0}, {110, 0}}, color = {0, 0, 127}));
  end if;
annotation(
    uses(Modelica(version = "4.0.0")));
end ConnectionNotShowing;

and look at the missing connection.

Expected Behavior

The connection is shown.

Additional Context

We are going to use OM for the IBPSA workshop at the Modelica Conference.
This issue could confuse users looking at the solution in the IBPSA.
If a quick fix is possible, it would be nice for the workshop.
