JavaScript namespaces not working with new JavaScript language service in VS2017

[andreabusi]

Visual Studio version: 2017 15.3.1

Code

if (typeof (MyNamespace) == "undefined") {
    MyNamespace = { __namespace: true };
}

MyNamespace.Foo = {
    doSomething: function () {
        MyNamespace.Foo.doSomething();
    }
};

Expected behavior:

Intellisense has to shows only valid suggestion, based on the namespace and current level. With legacy JavaScript language service it works propely:

Actual behavior:

In VisualStudio, if the new JavaScript language service is active, no valid Intellisense is provided:

Also, is impossible to use "Go To Definition" function:
