scrollEventThrottle has no effect on SectionList

[hugofelp]

scrollEventThrottle doesn't seem to make any difference when applied to SectionList. It works as expected with ScrollView.

Environment

Environment:
OS: macOS High Sierra 10.13.3
Node: 8.9.4
Yarn: 1.2.1
npm: 5.6.0
Watchman: 4.9.0
Xcode: Xcode 9.2 Build version 9C40b
Android Studio: 3.0 AI-171.4443003

Packages: (wanted => installed)
react: ^16.3.0-alpha.1 => 16.3.0-alpha.2
react-native: 0.54.2 => 0.54.2

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

I see there's a todo note around scrollEventTrottle in VirtualizedList -> https://github.com/facebook/react-native/blob/master/Libraries/Lists/VirtualizedList.js#L921. Are you running this on Android by any chance?

CC: @sahrens do you happen to have some context into what's left there to support it and whether this issue could be related?

This has effect even in <ScrollView>: https://snack.expo.io/rkgPA5FkH
