### Ionic Framework Version

v8.x

### Current Behavior

The value entered in an IonInput field disappears after the user returns from viewing a PDF document. This occurs when navigating away from the page containing the IonInput to view the PDF, and then navigating back to the original page.

### Expected Behavior

The expected behavior is for the IonInput to retain its value

### Steps to Reproduce

1. `yarn` or `npm i` for install dependencies
2. `yarn start` or `npm run start` to serve app on `0.0.0.0:4200`
3. open `{host}:4200` with safari on iphone (tested on iphone 13 and iphone 8)
4. click on "open pdf" link (safari will open pdf file in the same tab)
5. return back
