bug: Navigating to a page that has been been loaded before crashes app

Bug Report

Ionic version: [x] 4.11.2 (React)

Current behavior: Navigating to a page that has been loaded before breaks the app 100% of the time.

Expected behavior: The page should render when the app navigates to it.

Steps to reproduce: See StackBlitz below. Very easy to reproduce:

1. Assuming you are starting from Page 1, use the button on the bottom to go to Page 2
2. Use the button on the bottom of Page 2 to go back to Page 1.
3. The app will crash.

You can also start from Page 2 and it will crash when you return to Page 2.
