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?

if (style1 == null || style2 == null) {
    return;
  }
  if (shallowEqual(style1, style2)) {
    return;
  }
  var componentName = component._tag;
  var owner = component._currentElement._owner;
  var ownerName;
  if (owner) {
    ownerName = owner.getName();
  }
  var hash = ownerName + '|' + componentName;
  if (styleMutationWarning.hasOwnProperty(hash)) {
    return;
  }
  styleMutationWarning[hash] = true;
  warning(
    false,
    '`%s` was passed a style object that has previously been mutated. ' +
    'Mutating `style` is deprecated. Consider cloning it beforehand. Check ' +

    componentName,
    owner ? 'of `' + ownerName + '`' : 'using <' + componentName + '>',
