Android Splash screen get visible again after using `_system`

# Bug Report

## Problem
Splash screen get visible again after open a `_system` URL and return to app on Android devices.

### What is expected to happen?
Is expect to app hold the same state before open a url externaly (`_system` target).

### What does actually happen?
Using `_system` target, the URL opens as usual, but when the user returns to app, the splash become visible again for some milliseconds. In some cases, the app restarts.

## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Reproduce the behavior using the linked full source-code example and the this.inAppBrowser.create('https://google.com', '_system') call on Android with Cordova-android 14.0.1. Trace the Android app lifecycle when returning from the external URL; done means the app retains its prior state without showing the splash screen or restarting.
