**Do you want to request a *feature* or report a *bug*?**
Bug? (not a biggy - not sure if IE11 is support for development)

**What is the current behavior?**

IE11 seems to always throw a warning for hydration failures
eg

> **Warning: Prop `style` did not match. Server: "text-decoration: none;" Client: "text-decoration:none"**

Note: there is a space between the colon and none from Server, Client has no space

**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 for React 16: https://jsfiddle.net/Luktwrdm/, template for React 15: https://jsfiddle.net/hmbg7e9w/).**

Have a SSR rendered component, using inline styles
```
                       <a href="/page1" style={{ textDecoration: "none" }}>
                            <h1 className="splash-head">Go to Page1</h1>
                        </a>
```

Then hydrate it on IE11
`ReactDOM.hydrate(component, document.getElementById("app"));`

This **doesnt** occur in either Chrome or Firefox

**What is the expected behavior?**

No warning

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

React: 16.1.1
Browser: IE11
