Abort transition in willTransition and Browser Back button

Clik here to view.

I noticed a strange behavior in Ember … I’m trying to cancel a transition in the willTransition hook. For example, I’m on “page2” and I’m from “page1”. When I click on the link “page1”, no problem: the transition is canceled and the url doesn’t change. On the other hand, when I use the back button of the browser, the url changes first (I see the url of page1 in the bar) then the transition is canceled. The problem: I’m still on page2 but I now have the url of page1 !!! Is this a bug?

My route2.js code to simulate this behavior (here I use confirm but in my prod code I use bootbox):

import Route from '@ember/routing/route';

export default Route.extend({
  actions: {
    willTransition(transition) {
      if (!transition.data.force) {
        transition.abort();
        const r = confirm("Do you want to cancel transition?");

        if (r === false) {
          transition.data.force = true;
          transition.retry();
        }
      }
    }
  }
});

Thanks for your help,
