Report a bug.

**What is the current behavior?**
`<select>` element's `onChange` event is fired with incorrect `selectedIndex` and `value`, like it hasn't actually changed. This happens only if the element has been rendered under another React DOM root, see the example in the link below.

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem**
https://jsfiddle.net/martinsb/wd54vmmj/7/

**What is the expected behavior?**
`onChange` callback handlers should receive events with those values that user has actually selected. In the test case above, for example, when choosing "Two", I expect to have the following console output: `Change event, selectedIndex: 1, value: 2`

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**
The bug is observed with `react` and `react-dom` packages version `16.0.0-beta.3`. Latest stable version (`15.6.1`) works just fine.
