After create tabs page, but every page reload (livereload) the Tabs missing (same, on root tabs or subspage).

app.component.ts

import { Component } from '@angular/core';
import { Platform } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

import { TabsPage } from '../pages/tabs/tabs';

@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  rootPage:any = TabsPage;

  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      statusBar.styleDefault();
      splashScreen.hide();
    });
  }
}

tabs.ts

import { Component } from '@angular/core';
import { IonicPage, NavController } from 'ionic-angular';

@IonicPage()
@Component({
  selector: 'page-tabs',
  templateUrl: 'tabs.html'
})
export class TabsPage {

  tabsHomeRoot = 'TabsHomePage'
  tabsFavoriteRoot = 'TabsFavoritePage'
  tabsAddRoot = 'TabsAddPage'
  tabsSearchRoot = 'TabsSearchPage'
  tabsAccountRoot = 'TabsAccountPage'


  constructor(public navCtrl: NavController) {}

    <ion-tab [root]="tabsFavoriteRoot" tabUrlPath="tabs-favorite" tabTitle="Tabs favorite" tabIcon="information-circle"></ion-tab>
    <ion-tab [root]="tabsAddRoot" tabUrlPath="tabs-add" tabTitle="Tabs add" tabIcon="information-circle"></ion-tab>
    <ion-tab [root]="tabsSearchRoot" tabUrlPath="tabs-search" tabTitle="Tabs search" tabIcon="information-circle"></ion-tab>
    <ion-tab [root]="tabsAccountRoot" tabUrlPath="tabs-account" tabTitle="Tabs account" tabIcon="information-circle"></ion-tab>
