[iOS] The scroll position of the multiline TextInput affects the ScrollView auto-scroll when the keyboard opens/closes

Description

On iOS, when using a ScrollView with automaticallyAdjustKeyboardInsets and a multiline TextInput, the scroll position of the TextInput affects how the ScrollView auto-scrolls when the keyboard opens or closes.

Steps to reproduce

<ScrollView automaticallyAdjustKeyboardInsets>
   // Any content above the TextInput to position it at the bottom of the screen
   <TextInput multiline style={{ height: 100 }} /> // multiline TextInput with fixed height and many lines of text (let say 20)
   // More content to allow the ScrollView to scroll if needed
</ScrollView>

1. ScrollView with automaticallyAdjustKeyboardInsets
2. Content above the TextInput to fill the screen
3. Multiline TextInput with fixed height and many lines of text
4. Content below the TextInput to allow the ScrollView to scroll if needed
5. Focus on the input and scroll it to the end
6. Scroll the ScrollView to align the TextInput at the bottom of the screen
7. Focus on the last line in the TextInput
8. The keyboard slides up, and the ScrollView scrolls too much
9. With the keyboard open, scroll the ScrollView to align the TextInput at the bottom of the screen (above the keyboard)
10. Close the keyboard
11. The ScrollView scrolls up

Commencez par le reproducer iOS Snack obligatoire et comparez le comportement de ScrollView et de multiline TextInput lors de l’ouverture et de la fermeture du clavier. Suivez la gestion de automaticallyAdjustKeyboardInsets, puis vérifiez que ScrollView ne défile plus trop loin à l’ouverture du clavier et ne se décale pas vers le haut à sa fermeture.
