HtmlElementView Key Strokes interfering with primary ScrollView

### Steps to reproduce

1. Paste the code below in a fresh flutter project
2. Try to type in the html input field every character works but not the space and enter (space scroll the flutter scrollview instead)

### Expected results

I want the event to be caught by the html input element and the space to be written to the input field

### Actual results

Nothing is written to the input field and the scrollview is scrolling

### Code sample

Code sample

```dart
import 'package:flutter/material.dart';
import 'package:web/web.dart' as web;
import 'dart:ui_web' as ui;

void main() {
ui.platformViewRegistry.registerViewFactory(
'my-html-view', // Unique identifier for the view
(int viewId) {
final div = web.HTMLInputElement();
div.style
..width = '500px'
..height = '100px';

return div;
},
);

runApp(const MyApp());
}

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

@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Stack(
alignment: Alignment.center,
children: [
CustomScrollView(
primary: true,
slivers: [
SliverList(
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) => ListTile(title: Text('Item #$index')),
childCount: 300,
),
),
],
),
const SizedBox(
width: 500,
height: 100,
child: HtmlElementView(viewType: 'my-html-view'),
),
],
),
),
);
}
}

```
