If "getOwnPropertyDescriptor" trap is null or undefined, [[GetOwnProperty]]
|
|
call is properly forwarded to [[ProxyTarget]] (which is also a Proxy object).

[[GetOwnProperty]] ( P )
|
|
|
|
[...]
|
|
5. Let target be O.[[ProxyTarget]].
|
|
6. Let trap be ? GetMethod(handler, "getOwnPropertyDescriptor").
|
|
7. If trap is undefined, then
|
|
a. Return ? target.[[GetOwnProperty]](P).
