[Bug] iOS scroll to cursor issue

### Bug Description

I need to implement AppflowyEditor with dynamic height.
It worked correctly in 1.4.4 version, but version 2.1.0 breaks flow

### How to Reproduce

```dart
class HomeSamplePage extends StatefulWidget {
static const String route = '/sample';

const HomeSamplePage({Key? key}) : super(key: key);

@override
State createState() => _HomeSamplePageState();
}

class _HomeSamplePageState extends State {
final _descriptionScroll = ScrollController();
final _descriptionFocusNode = FocusNode();
late EditorState editorState;

@override
void initState() {
editorState = EditorState(
document: Document.blank(withInitialText: true),
);
_descriptionFocusNode.addListener(() {
setState(() {
//do refresh UI to show RichText buttons
});
});
super.initState();
}

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('Sample')),
body: SafeArea(
child: Container(
padding: const EdgeInsets.symmetric(horizontal: 16),
child: Column(
children: [
Expanded(
child: SingleChildScrollView(
child: Column(
children: [
TextFormField(
decoration: const InputDecoration(hintText: 'Title'),
),
const Divider(),
IntrinsicHeight(
child: AppFlowyEditor(
editorStyle:
AppflowyEditorStyles.getDescriptionStyles(
context),
editorState: editorState,
editorScrollController: EditorScrollController(
editorState: editorState,
scrollController: _descriptionScroll,
shrinkWrap: true,
),
focusNode: _descriptionFocusNode,
blockComponentBuilders:
AppflowyEditorStyles.getBuilders(
context, editorState),
),
),
const Divider(),
const Text('Some text under description'),
],
),
),
),
const Divider(),
Row(
children: [
OutlinedButton(
child: const Text('switch'),
onPressed: () async {
//some action, imitate real ui
},
),
],
),
const Divider(),
if (_descriptionFocusNode.hasFocus) ...[
const SizedBox(
height: 2,
),
//custom toolbar
RichTextToolbar(editorState: editorState),
const SizedBox(
height: 2,
),
],
],
),
),
),
);
}
}
```

### Expected Behavior

cursor is always visible
