This is a bug report.

**What is the current behavior?**

In Safari, the type of input field is not updated properly. Consider the example linked below. It is a React component that display a button and an input field. The type of input field will be toggled between file or text by clicking the button. The change of input type is not being reflected.

I believe this is an issue with Safari. Setting the `type` property in Safari does not affect what is being rendered:

``` javascript
var a = document.createElement("input");
a.type = "text";
document.body.appendChild(a); // A text input is shown
a.type = "file"; // The input remains a text input in Safari.
```

**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/reactjs/69z2wepo/).**

**What is the expected behavior?**

The input type should be changed, as in Chrome and Firefox.

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

React: 15.1.0
ReactDOM: 15.1.0
Browser: Safari 9.1.1, Chrome 51.0.2704.103, Firefox 47.0
OS: OS X 10.11.5

var div = ownerDocument.createElement('div');

          div.innerHTML = `<${type}></${type}>`;

        } else if (props.is) {
          el = ownerDocument.createElement(this._currentElement.type, props.is);
        } else {

      ReactDOMComponentTree.precacheNode(this, el);
      this._flags |= Flags.hasCachedChildNodes;
      if (!this._hostParent) {
        DOMPropertyOperations.setAttributeForRoot(el);
      }
      this._updateDOMProperties(null, props, transaction);
      var lazyTree = DOMLazyTree(el);
