Current Behavior

Related to #2402 (closed), but still reproducible on 6.2.0-beta.3

On the desktop screen, only the Flutter application is open. When the program is minimized, the webview area of the application prevents the mouse from interacting with the desktop.

Expected Behavior

It should be possible to interact with the desktop using the mouse when the application is minimized or the window is moved to a different position.

Steps with code example to reproduce

Details

Reproduction steps on Windows:

1. Run the app on Windows desktop (flutter run -d windows).
2. Wait until the web page is fully loaded.
3. Click the window minimize button (_) in the title bar.
4. Try clicking desktop icons in the area where the app window was previously shown.
5. (Optional) Restore the app and repeat minimize/restore several times.

Use this minimal app:

import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';

void main() {
  runApp(const MaterialApp(home: ReproPage()));
}

class ReproPage extends StatelessWidget {
  const ReproPage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: InAppWebView(
        initialUrlRequest: URLRequest(
          url: WebUri('https://google.com'),
        ),
      ),
    );
  }
}
