Bug Report

Ionic version:

[x] 4.5.0

Current behavior:

Route in tabs.router.module.ts

const routes: Routes = [
  {
    path: 'tabs',
    component: TabsPage,
    children: [
      {
        path: '',
        redirectTo: '/tabs/(home:home)',
        pathMatch: 'full',
      },
      {
        path: 'home',
        outlet: 'home',
        component: HomePage
      },
      {
        path: 'chats',
        outlet: 'chats',
        component: ChatsPage
      },
...

Logging failed for ionViewWillLeave in chats.page.ts

ionViewWillEnter() {
  console.log('ionViewWillEnter');  // <- In console when entering
}
ionViewWillLeave() {
  console.log('ionViewWillLeave');  // <- Not in console when leaving
}

Expected behavior:

ionViewWillLeave has to trigger when leaving the page

Steps to reproduce:

1. Add routing from page to tabs.router.module.ts
2. Add ionViewWillLeave Event to page.ts file

Route in app-routing.module.ts

const routes: Routes = [
  { path: '', loadChildren: './tabs/tabs.module#TabsPageModule' },
  { path: 'chats', loadChildren: './chats.module#ChatsPageModule' },
