I've run into an issue where on Firefox and Chrome, at least, properties of object literals I've created are being frozen. I'm including a screenshot of the output of the below code snippet since I'm having a hard time believing this is true. I must have something on my end causing this, or I just really don't understand JavaScript.

```js
let b = { foo: { bar: 2 }, baz: 9 };

console.log("b:", Object.isFrozen(b));
console.log("foo:", Object.isFrozen(b.foo));
console.log("foo.bar:", Object.isFrozen(b.foo.bar));
console.log("baz:", Object.isFrozen(b.foo.baz));
```
