[js code hints] parameter type later becomes variable name when passing object as param to a function

[jodyzhang]

1. copy/paste following code snippet

var D1 = { propD : 1 },
    D2 = { propD : 2 };

function funE(paramE1, paramE2) {
    'use strict';
}
funE(D1, D2);
funE(

1. check code hint for funE(, now it returns function type is: funE(paramE1: D1, paramE2: D2)

Expect: it is either ? or Object? for paramE1, paramE2?
