can scripted lookup symbols across different files

[larryhe]

It looks like that scripted can't jump to the symbol definition correctly across different files. for example, i have below two files, on line 2 of foo.js, I can't jump to bar1 definition which is bar.js file. but on line 3 of foo.js, i can correctly jump to foo2 definition. Is this the restriction of editor? Thanks.
foo.js
function foo1(){
var a = bar1(); //line 2
foo2();//line3
}
function foo2(){
console.log('foo 2 running');
}
and
bar.js
function bar1(){
return 10;
}
