Object on ES7 Class Highlights Closing Bracket Red

![Preview](http://i.imgur.com/h0T0Oix.png)

When you define an object on ES6 class, closing bracket of that object will get highlighted in red. When you define a number, a string, an array or a lambda instead, everything works.

``` javascript
class Thing {
    foo = {}
}

class OtherThing {
    bar = 42
}
```

You can reproduce this on `master` branch.
