<pre>Please consider the following code:
```
var target =
{
get prop()
{
console.log(this == proxy) // => `false`, should be `true`
}
}
var proxy = new Proxy(target, {})
proxy.prop
```
`proxy.prop` calls `[[Get]]` on `proxy` with `"prop"` as key and `proxy` as receiver.
Proxy's `[[Get]]` method checks for `get` trap, it is missing, so it should call `[[Get]]` on `target` with **the same** parameters.
However, JSC does not pass receiver, thus `prop` getter is called with context of `target`, not `proxy`.
Both V8 and SpiderMonkey implement this correctly.
