1596100 - Can't expand object with symbol keys

Status: NEW

(DevTools :: DOM, defect, P3)

Description

[Nicolas Chevobbe [:nchevobbe]]

Steps to reproduce

1. Navigate to data:text/html,<script>window.a = {[Symbol("hello")]: {a: [1,2,3]}};</script>
2. Open the DOM panel

Expected results

a should be expandable

Actual results

a isn't expandable

---

it only happens if there's only Symbol-keyed properties, with the following data:text/html,<script>window.a = {b: 1, [Symbol("hello")]: {a: [1,2,3]},[Symbol()]: {b: [4,5,6]},[Symbol()]: {[Symbol("c")]: [4,5,6]},};</script> I can expand a (but symbols are not displayed).

Thanks for the report Nicolas, I can reproduce that on my machine Win10 + Nightly.
