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?

var current = tracker.getValue();
    elem.value = value;
    tracker.setValue(current);
  }
