Steps to Reproduce:
1. Open https://jsfiddle.net/hstangl/pJgyu/39413/embedded/result/ on iOS Safari
2. Tap on the first select field, reading "3"
3. Directly tap on the second select field, reading "A"
Safari should show the correct values for each of the select fields, without changing them without user interaction.
After tapping on the first select field, the option picker comes up with "3" selected (good).
After tapping on the second select field, the option picker comes up with "A" shown as selected on the option picker (good), but "C" shown on the web page and actually being set on the form field (bad).
This happens only on iPhone where select elements use the picker wheel and the value is only committed when losing focus.
It works correctly when moving focus using the arrow keys.
