ES6 maps in Typescript in Node.js

Hay,

I made something like that : 

this.mapTest = new Map();
this.mapTest.set('test', 'Im here');

console.log(this.mapTest.get('test'));

Unfortunattelly I put breakpoint after console log and my this.mapTest is "clear". I can't see any its values. 

But I can search key in map and see its value in concole : 

Does intellij somehow support ES6 Map in Nodejs debbug configured with Typescript (source map) ?
