Steps to reproduce the problem:
1. Create an object.

var obj = {};

2. Add a public property to it.

obj.x = 1;

3. Add a symbol property to it.

var sym1 = Symbol("t");
obj[sym1] = 11;

4. Add another public property to it.

obj.y = 2;

5. Access the values in the object. 

console.log(Object.values(obj));

What is the expected behavior?
The value array should be [1, 2], as Symbols property wouldn't be enumerated. 

What went wrong?
However, the value array comes out as [1]. The second public property is skipped.

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 66.0.3359.139  Channel: stable
OS Version: 10.0
Flash Version: 

I have also noticed that if I add two symbol keys to the object, the result of `Object.values` will omit two public keys from the result. I have included other two test cases in the attachment.

I tried iterating over the keys using `for..in` - and that works fine.

The result of `Object.keys` is fine as well.

Note: I just learned about ES6 Symbols today, so I'm not 100% sure about this. But it works as I expect in other browsers, so it does seem like a bug.
