Unchanged hasMany causing isDirty

I’m working on some code to autosave my model. It looks like:

export default Route.extend({
  autosave: task(function * () {
    yield timeout(3000);
    this.get('model').save();
  }).restartable(),

  model(params) {
    return this.store.findRecord('task', params.taskId);
  },

  afterModel(model) {
    this.set('model', model);
  },

  modelChanged: observer('model.isDirty', function() {
    if(this.get('model.isDirty')) {
      window.console.log(this.get('model').changed());
      this.get('autosave').perform();
    }
  })
});

I have the model configured with: changeTracker: { trackHasMany: true, auto: true, enableIsDirty: true }

When I change a string “deliverables” attribute in the model, I get on the console:

{deliverables: Array(2), subscribers: true}
{subscribers: true}
{}

Why does it think subscribers changed? subscribers is modeled as: subscribers: hasMany('user', {inverse: null})

wow … this is blast from the past. but i would suggest you make a PR and write a test or make the fix in the change tracker repo, that way I can check it out and see if it makes sense. I still don’t follow the test and for sure you can’t do a fix where you open the ember-data store. that not going to make anyone happy. but if you can do a better fix or explain the issue in a test ( in change tracker ) then I happy to check it out

oooo … this sounds like a bug.
can you do me a huge favour and make a test to show this ( broken behaviour ) and slap it in a PR so I can fix it / see the breaking thing / check it out that way?
