Description

On iOS, if a TextInput has similar lineHeight and fontSize style props, the field doesn't scroll when the length of the value overflows its container.

I've done some experiments with trial and error and it appears that when they're within 2pt of each other, the issue happens.

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!
