In my render method I have something like

```
<input type={dynamicTypeValue} value={dynamicValue} />
```

If I first render this input as a number, (e.g. `dynamicTypeValue = 'number'; dynamicValue = 5`) but then change the input to a string: (`dynamicTypeValue = 'string'; dynamicValue = '01/01/2016'`) I get a warning 
that the new value is not a valid number:

```
The specified value "01/01/2000" is not a valid number. The value must match to the following regular expression: -?(\d+|\d+\.\d+|\.\d+)([eE][-+]?\d+)?
DOMPropertyOperations.js:142 The specified value "01/01/2012" is not a valid number. The value must match to the following regular expression: -?(\d+|\d+\.\d+|\.\d+)([eE][-+]?\d+)?
```

Is this expected behavior?

break;
      case 'select':
        ReactDOMSelect.mountWrapper(this, props, hostParent);
        props = ReactDOMSelect.getHostProps(this, props);
        transaction.getReactMountReady().enqueue(trapBubbledEventsLocal, this);
        break;
      case 'textarea':
        ReactDOMTextarea.mountWrapper(this, props, hostParent);
        props = ReactDOMTextarea.getHostProps(this, props);
        transaction.getReactMountReady().enqueue(trackInputValue, this);
        transaction.getReactMountReady().enqueue(trapBubbledEventsLocal, this);
        break;
    }
    assertValidProps(this, props);
    
    
    var namespaceURI;
    var parentTag;
    if (hostParent != null) {
      namespaceURI = hostParent._namespaceURI;
      parentTag = hostParent._tag;
    } else if (hostContainerInfo._tag) {
      namespaceURI = hostContainerInfo._namespaceURI;
      parentTag = hostContainerInfo._tag;
    }
    if (namespaceURI == null ||
        namespaceURI === DOMNamespaces.svg && parentTag === 'foreignobject') {
      namespaceURI = DOMNamespaces.html;
    }
    if (namespaceURI === DOMNamespaces.html) {
