QuickInfo Does not Return Documentation For Attribute

[mjbvz]

From http://stackoverflow.com/questions/42126703/visual-studio-code-display-jsdoc-for-attribute

TypeScript Version: 2.2.0-dev.20170207

Code

interface Point {
    /** The x property */
    x: number;
    /** The y property */
    y: number;
}

const p: Point = <Point>{
    x: 10,
    y: 10,
};

p.x;

Expected behavior:
quickinfo for the x in x:10 shows the property info along with the documentation for x

Actual behavior:

Here's hovering over the x in x:10

        "offset": 6
    },
    "displayString": "(property) x: number",
    "documentation": ""
}

vs hovering over p.x:

    },
    "end": {
        "line": 13,
        "offset": 4
    },
    "displayString": "(property) Point.x: number",
    "documentation": "The x property "
}

Note that completionEntryDetails for x in x:10 does return the documentation for Point.x

How to make it works properly with no-typescript projects like ES6+Babel projects?
