### Other API Details

```Shell
`npm --version`
> 10.7.0

`node --version`
> v20.11.0
```

### Platforms Affected

- [ ] iOS
- [X] Android
- [ ] Web

### Current Behavior

After redirecting to an external URL that is allowed in the `server.allowNavigation` config setting, an android app reports being on a web platform instead of android.
This can be seen by calling `Capacitor.getPlatform()` (which returns `android` before redirecting and `web` after redirecting) or by trying to use a native API, which will either fallback to the web version of the API, or fail to run at all

All this works on iOS, where after redirecting, the app can still use native iOS APIs

### Expected Behavior

After redirecting, the android app should still have access to all the native Android APIs (and report itself as being an Android platform)

### Project Reproduction

### Additional Information

Reproduction details are in the repo, but the basic reproduction steps are as follows:

1. Serve a valid capacitor app on your computer (i.e. with `npx serve .`)
2. Add your computer's IP to the `server.allowNavigation` capacitor config setting
3. Load the application on your (real or simulated) device
4. Notice that `Capacitor.getPlatform()` returns `android` on android and `ios` on iOS
5. Redirect to the hosted server (any method works, can be `window.location.assign()`, `window.location.href = ""`, `window.location.replace()`, or redirecting through a form
6. Notice that `Capacitor.getPlatform()` now returns `web` on android but still `ios` on iOS

Here are videos showing the issue. Even though these were recorded on a simulator, the results are identical to a physical device

Our use case is to have one app that connects to different backends on different subdomains, very similar to Slack. So far everything is working except the android app loses access to its native APIs
