Describe the Bug
Back button breaks tabs url
http://localhost:8100/tabs instead of http://localhost:8100/tabs/(home:home)

Steps to Reproduce

• Created new project with tabs template ionic start New tabs --type=angular
• Added new page ionic g page settings and added back button to generated settings.page.html ion-toolbar element <ion-buttons slot="start"><ion-back-button></ion-back-button></ion-buttons>
• added link to the new page on home.page.html <a [routerLink]="['/settings']">Settings</a>
• run ionic serve opens http://localhost:8100/tabs/(home:home) in browser - tab buttons work ok
• click on Settings link, opens http://localhost:8100/settings
• now click on back button in header, opens http://localhost:8100/tabs and tabs do not work anymore (show correctly, but tapping on tab button reloads application)

Other comments
If I use browser back instead of back button, the app works fine!
