Bug with Meteor-flow-router-title

import { FlowRouter } from 'meteor/ostrio:flow-router-extra';

const test = new ReactiveVar(1);

Meteor.setInterval(() => {
  test.set(test.get() + 1);
  console.log(`new:${test.get()}`);
}, 1000);

FlowRouter.route('*', {
  name: 'Test.name',
  action() {
    console.log('rendered');
  },
  title() {
    const t = test.get();

    console.log(`change title:${t}`);

    return `count ${t}`;
  },
});
