Does a change in query params cause a transition?

controllers.application.js

import Ember from 'ember';

export default Ember.Controller.extend({
  appName: 'Ember Twiddle',
  
  queryParams: ['a'],
  
  actions: {
    eh() {
    	this.set('a', Math.random());   
    }
  }
});

router.js

import EmberRouter from '@ember/routing/router';
import config from './config/environment';

const Router = EmberRouter.extend({
  location: 'none',
  rootURL: config.rootURL,
});

Router.map(function() {
});

export default Router;

routes.application.js

import Ember from 'ember';
import { inject as service } from '@ember/service';

export default Ember.Route.extend({
 router: service('router'),
  init() {
    this._super(...arguments);
 
        
    this.on('routeDidChange', (transition) => console.log('didChange', transition));
    this.on('routeWillChange', (transition) => console.log('didChange', transition));
  }
});

templates.application.hbs

<h1>Welcome to {{appName}}</h1>
<br>
<br>
{{outlet}}
<br>
<br>
<button onClick={{action 'eh'}}>change qp</button>
