**Do you want to request a *feature* or report a *bug*?**
I report a bug.
**What is the current behavior?**
When resetting a form which contains a select with a defaultValue, the selected option becomes the first option element in the list, not the one with value=defaultValue.
**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template: https://jsfiddle.net/ebsrpraL/).**
I have put a piece of code here : 
https://codepen.io/zehiro/pen/YrxZWw?editors=1111#0

Click on the reset button, which just does a form.reset() on the form.
**What is the expected behavior?**
I expect the select to select the option with value=defaultValue (like applying a form.reset() on a `<input/>`
**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**
React-DOM 15.6.2.
It seems to be browser independent (tried with Chromium 61 and firefox 55 for Fedora).
I didn't try this on prior version of React.
