RNAlert.alert causes KASV to scroll to top

[jagert]

I'm using KASV like this:

<View style={{flex: 1}}>
  <KeyboardAwareScrollView
    alwaysBounceVertical={false}
    showsVerticalScrollIndicator={false}
    style={{flex: 1}}
    keyboardShouldPersistTaps="handled"
    extraHeight={100}
  >
    <View style={{height: 1000}} />
    <TouchableOpacity onPress={() => Alert.alert('Hello', 'world!')}>
      <View>
        <Text>Press me</Text>
      </View>
    </TouchableOpacity>
    <TextInput placeholder={'Give me text'} />
  </KeyboardAwareScrollView>
</View>

and encountered strange behavior. Steps to reproduce:

• scroll view down
• focus TextInput:
  • keyboard appears
  • view scrolls under the input
• press TouchableOpacity:
  • keyboard disappears
  • view scrolls up to the top, TextInput goes off screen
  • alert appears
• press OK:
  • alert disappears
  • keyboard appears
  • view scrolls under the input

Expected behavior:

• scroll view down
• focus TextInput:
  • keyboard appears
  • view scrolls under the input
• press TouchableOpacity:
  • keyboard disappears
  • view scrolls up, but not TextInput is still visible
  • alert appears
• press OK:
  • alert disappears
  • keyboard appears
  • view scrolls under the input

Diving into code shows that 'keyboardWillHide' fired twice on calling Alert.alert. That causes defaultResetScrollToCoords to be nulled after first 'keyboardWillHide' and the second 'keyboardWillHide' causes scrollToPosition(0, 0, true).

So, guys, there is a way to handle this case? Looks like that it's a bug of Alert, because opening RNModal fires 'keyboardWillHide' only once, but googling gives no answer..
