Steps to reproduce

  1. Long press TextField to open magnifier
  2. While still long pressing, put the app to background with another finger (-> cancel long press)
  3. Open the app again

Expected results

Magnifier should close, similarly to when the long press ends (without cancelling)

Actual results

Magnifier is stuck on the screen, even if you scroll away from the textfield

Code sample

Example code 
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Magnifier bug',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: const MyHomePage(title: 'Magnifier bug'),
    );
  }
}

class MyHomePage extends StatelessWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: ListView(
        children: [
          const Text(
            "Long press to trigger the magnifier and while holding down, put the app into background. When coming back to app, the magnifier should be stuck on screen.",
          ),
           TextField(
            decoration: InputDecoration(hintText: "write something"),
          ),
          ...List.generate(
            20,
            (i) => GestureDetector(
                onTap: (){
              FocusScope.of(context).unfocus();
            },
              child: Container(
                height: 50,
                width: double.infinity,
                color: i % 2 == 0 ? Colors.red : Colors.blue,
              ),
            ),
          ),
        ],
      ),
    );
  }
}
