bug

**What is the current behavior?**

React interactivity lost, React crash?

**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/).**

Run with react-dom.development.js in IE11, not sure exactly what the exact repo steps are the fix I've attempted for IE11 was to simply pass an empty string.

~~~
var normalizeHTML = function (parent, html) {
    if (!testDocument) {
      testDocument = document.implementation.createHTMLDocument(""); // fix for IE11 here
    }
    var testElement = parent.namespaceURI === HTML_NAMESPACE ? testDocument.createElement(parent.tagName) : testDocument.createElementNS(parent.namespaceURI, parent.tagName);
    testElement.innerHTML = html;
    return testElement.innerHTML;
  };
}

MDN docs [here](https://developer.mozilla.org/en-US/docs/Web/API/DOMImplementation/createHTMLDocument).

**What is the expected behavior?**

Well, that React does not crash in dev mode and that interactively continues to work.

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

`react@16.0.0` IE11
