## Steps to Reproduce

This is minimum code

<details>
<summary>code sample</summary>

```dart
import 'package:flutter/material.dart';
import 'package:flutter/scheduler.dart';

class SamplePage extends StatefulWidget {

  SamplePage(): super();

  @override
  SamplePageState createState() => SamplePageState();
}

class SamplePageState extends State<SamplePage> with WidgetsBindingObserver {
  ScrollController _scrollController = ScrollController();

  @override
  void initState(){
    super.initState();
    SchedulerBinding.instance?.addPostFrameCallback((_){
      setState(() { });
    });    
  }    

  Widget build(BuildContext context){
    List<Widget> widgetList = [
      Center(child: TextField(maxLines: null, ),),
      Divider(),
      Center(child: TextField(maxLines: null, ),),
      Divider(),
    ];

    Widget bodyScaffold = Scaffold(
      body: Scrollbar(
        controller : _scrollController, 
        child      : SingleChildScrollView(
          controller  : _scrollController,
          child       : Column(
            children : widgetList,
          )
        )
      )
    );

    return bodyScaffold;
  }
}
```
</details>




1. Run `flutter run -d chrome `.
2. Input text in upper TextField. ( I used japanese )
3. Use tab key to select word from suggestion box.

**Expected results:**
Not change focus to other text field and select word from suggestion box

**Actual results:**
Focus changes to other text field and the first suggestion is selected
