text field loosing state on `render`

### Expected behavior
Input fields should retain their state (and possibly focus as well as cursor position) regardless of `emitter.emit('render')`

### Actual behavior
Text input fields loose their state/value on rendering.

### Steps to reproduce behavior
Minimally adjusted code from the README shows the described behaviour: http://requirebin.com/?gist=829488013f4333ed528825df65c6a406

Start with the README example and the linked RequireBin reproduction, then trace how emitter.emit('render') updates text input fields. The issue is done when rendering preserves each input's value, and, where supported, its focus and cursor position.
