[iOS] Autocorrect highlight does not go away if you scroll

### Steps to reproduce

1. In a text field, type a misspelled word like `grept`. Don't accept the autocorrect suggestion.
2. Do a swipe gesture to scroll.

### Expected results

Scrolling accepts the autocorrect suggestion. The autocorrect highlight is no longer visible.

### Actual results

Scrolling accepts the autocorrect suggestion, but the autocorrect highlight remains visible at the text field's original location, which is clearly incorrect as the text field scrolls away.

### Code sample

Code sample

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

void main() {
runApp(
MaterialApp(
home: Scaffold(
body: ListView.builder(
itemCount: 100,
itemBuilder: (context, index) => TextField(),
),
),
),
);
}
```
