I have the following code:

```
import React, { Component, PropTypes } from 'react';
import LinkedStateMixin from 'react-addons-linked-state-mixin';
import ReactMixin from 'react-mixin';
import s from './LoginPage.scss';
import withStyles from '../../decorators/withStyles';

const title = 'Log In';

@withStyles(s)
class LoginPage extends Component {

constructor() {
super();
this.state = {
user: '',
password: ''
}
}

static contextTypes = {
onSetTitle: PropTypes.func.isRequired,
};

componentWillMount() {
this.context.onSetTitle(title);
}

login(e) {
e.preventDefault();
console.log(e)
}

render() {
return (

}

ReactMixin(LoginPage.prototype, LinkedStateMixin);

export default LoginPage
```

The react-mixin functionality works as intended without a decorator, however, when a decorator is included I get the error "this.linkState is not a function'

Start by reproducing the supplied LoginPage example, then inspect the withStyles decorator and the ReactMixin(LoginPage.prototype, LinkedStateMixin) call. Compare the decorated and undecorated cases to determine why linkState is missing; done when the decorator no longer prevents the mixin method from working and the behavior is covered by a regression test.
