Show Proper Suggestions within Class Body

[audinue]

TypeScript Version: 2.2.2

Code

class Component {

    /**
     * Called when this component is updated.
     */
    componentUpdated () {
    }
}

class MyComponent extends Component {

    // CTRL+SPACE here...
}

Expected behavior:
TypeScript [language service] shows proper sugestions including the documentation for the class members.

For example:

constructor
toString
componentUpdated

Actual behavior:

TypeScript showed irrelevant suggestions.
