Bug Report

Ionic version:

[x] 4.10

Current behavior:

When you open ion-menu and navigate to a page and then go back the menu is no longer visible but if you click anywhere on the screen it then reappears and closes immediately. This only occurs on iOS.

Expected behavior:

The menu should be visible after opening it and navigating to a page and back.

Steps to reproduce:

Create an Ionic app with the iOS platform and add an ion-menu that includes an ion-item that uses routerLink to navigate to another page. Then click an ion-back-button.

Other information:

This only occurs on iOS and I believe this began with with version 4.8 or 4.9.
