Editing of fixed attribute for variables with enable=false

[abuntrock]

Description

If a variable declaration includes the annotation enable=false it cannot be edited but its modifiers like fixed can.

Steps to Reproduce

1. Load the following modelica package

package FixedEnabled
   
model MainClass
    Real realVariable(start=0.0) = time annotation(
      Dialog(showStartAttribute=true, enable = false));
  end MainClass;

  model ClassWithInstance
  MainClass mainClass annotation(
      Placement(transformation(extent = {{-10, -10}, {10, 10}})));
  equation

  end ClassWithInstance;
end FixedEnabled;

2. Open the parameter dialog of mainClass' in ClassWithInstance`. It looks like this::

The start value realVariable.start cannot be edited but the fixed and final modifiers can. This can cause problems. In this minimum example the simulation fails if realVariable.fixed=true is set. And this simulation failure cannot be prohibted by enable=false right now.

Expected Behavior

The modifiers (especially fixed) of variables, whose start value cannot be edited because of enable=false, cannot be edited as well.

Addition: We would expect the same for the modifiers of parameters (like final) that have enable=false.
