Changeset Boolean Bug

controllers.application\.js

import Controller from '@ember/controller';
import { EmberChangeset, Changeset } from 'ember-changeset';

class MyChangeset extends EmberChangeset {
  // NOTE using the default safeSet for only type boolean fixes the issue
  safeSet(obj, key, value) {
    if (typeof value.value === 'boolean') (obj[key] = value);
    
    return super.safeSet(obj, key, value);
  }
}

import { action, computed } from '@ember/object';

export default class ApplicationController extends Controller {
  appName = 'Ember Twiddle';

	@computed()
  get changeset() {
  	return Changeset({ isRunning: true }, function() {}, {}, { changeset: MyChangeset });
  }

	@action
	toggleRunning() {
  	this.changeset.set('isRunning', !this.changeset.get('isRunning'));
  }
}

templates.application\.hbs

<h1>Welcome to {{this.appName}}</h1>
<br>
<br>
{{this.changeset.isRunning}}
<br>
<br>
<button {{on 'click' this.toggleRunning}}>Run!</button>

<Input @value={{this.changeset.name}}/>
