bugs on textinput when typing Korean and moves the cursor

Please provide the following:

  1. SDK Version:37
  2. Platforms(Android/iOS/web/all): ios

as stated in https://github.com/facebook/react-native/issues/19313

when I use stateful onChangeText api on textinput and move the cursor in between characters, it breaks to “오후의 ㅁㅏㅇㅣㅆㄴㅡㄴ 홍차” but it should be “오후의 맛있는 홍차”.

I initially thought it was bug on react native, but when I did the same thing in bare react native, it works fine.
