IE11 Windows 10 text area placeholder not rendering initially.

**What is the expected behavior?**

Placeholder should be visible on initial render.

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

16.0.0, IE11, Windows 10
Appears to be a regression in 16.0.0 - #6731
