Picker resets its selection back to the 1st row when it's removed and re-added to the window. This happens with single-column and multicolumn pickers.
Steps to reproduce:
- Create a project using the attached SinglePickerAddRemoveTest.js code.
- Build and run on iOS.
- Select the last row in the picker.
- Tap the "Remove" button.
- Tap the "Add" button.
- Observe the picker's current selection.
Picker resets its selection to the 1st row when re-added to the window.
