Unable to see the __proto__ chain in the debugger for objects with parent/prototype Object.create(null).

[exercising camel]

It seems that the debugger doesn't show the __proto__ slot/property for objects that have a parent of Object.create(null) in their prototype chain.


window.onload = function() {
    'use strict';

    var parent = Object.create(null);    // we can not see the __proto__ slot
//     var parent = Object.create({});   // we can     see the __proto__ slot
    parent.x   = [3];
    parent.inc = function() { this.x[0] += 1; };

    var self = Object.create(parent);
    self.inc();

    // correctly outputs 4 but we can't see the __proto__
    // slot when debugging (by hovering the mouse over the variable self);
    // the same is true about  browsing the 'Local scope' and the console.dir() method
    console.log(self.x[0]); // 4
};
