Proxy [[OwnPropertyKeys]] trap does not skip string keys when validating invariant:
* If the target object is not extensible, then the result List must contain all the keys of
the own properties of the target object and no other values.
info: |
Object.getOwnPropertySymbols ( O )
1. Return ? GetOwnPropertyKeys(O, Symbol).
GetOwnPropertyKeys ( O, type )
...
2. Let keys be ? obj.[[OwnPropertyKeys]]().
[[OwnPropertyKeys]] ( )
...
11. Let targetKeys be ? target.[[OwnPropertyKeys]]().
16. For each element key of targetKeys, do
a. Let desc be ? target.[[GetOwnProperty]](key).
b. If desc is not undefined and desc.[[Configurable]] is false, then
...
c. Else,
i. Append key as an element of targetConfigurableKeys.
...
18. Let uncheckedResultKeys be a new List which is a copy of trapResult.
...
22. If uncheckedResultKeys is not empty, throw a TypeError exception.
