scrollEventThrottle has no effect on SectionList #18441
Description
scrollEventThrottle doesn't seem to make any difference when applied to SectionList. It works as expected with ScrollView.

Steps to Reproduce
export default class App extends Component<Props> {
render() {
return (
<View style={styles.container}>
<ScrollView
scrollEventThrottle={ 1000 }
onScroll={ e => console.log( Date.now() ) }
>
<Text>ScrollView Text</Text>
</ScrollView>
<SectionList
renderItem={ ( { item } ) => <Text>SectionList Text</Text> }
sections={ [ {
title: 'section title',
data: [ 'item' ]
} ] }
scrollEventThrottle={ 1000 }
onScroll={ e => console.log( Date.now() ) }
/>
</View>
);
}
}
Expected Behavior
The events logged to the console should have at least 1000ms between them.
Actual Behavior
SectionList logs events at high rates regardless of the value passed to scrollEventThrottle
