Description

A ScrollView with a TextInput that uses transform:[{translateY:value}] causes the ScrollView to not be able to faithfully position the TextInput in the view. This would not really be a huge issue if instead of forcing the scroll back to the top, it did nothing. I have only been able to reproduce this on Android, both real device and simulator.

Reproducible Demo

1. Open the app
2. Tap the red input box
3. Scroll to it so it is in view
4. Type
5. On keystroke it scrolls it back to the top (presumably trying to scroll it into view.)

You are right, this seems like this is a real issue but unfortunately it's unlikely anyone will be able to spend time on this anytime soon. I'm going to close this issue but we are more than happy to receive a pull request with a fix for this!
