TypeScript Intellisense works differently if I define Object in Different Ways

问题

I am trying to convert some existing JavaScript code by using TypeScript, One example I am using is to create Highcharts classes, the Highcharts definition is from https://github.com/borisyankov/DefinitelyTyped/blob/master/highcharts/highcharts.d.ts

We all know HighchartsOptions has a property title.

If I define the object in this way, I have intellisense

But if I define object this way

I don't have the intellisense.

Any specific reason why Visual Studio behaves differently?

It's just a bug. See this issue on CodePlex to track when it gets fixed.
