After reviewing a bit, this is actually how the current "spec text" works. Since the proxy is transparent when it comes to private symbols, the [[Get]]
operation is forwarded directly to the target: Return ? target.[[Get]](P, Receiver)
(9.5.8 Step 7).
Although it was my intention to have an observable call to getPrototypeOf
, it was never actually spec'd that way in the first place!

Further proof:
const target = { test: true }
const proxy = new Proxy(target, {
get(target, key) {
// Imitate "transparent" proxy
return Reflct.get(...arguments);
},
getPrototypeOf() {
throw new Error('observable');
}
});
console.assert(proxy.test === true);
const sub = Object.create(proxy);
console.assert(sub.test === true);
In fact, no traps are fired (minus the get
trap, because I'm imitating):
const target = { test: true }
const proxy = new Proxy(target, new Proxy({}, {
get(target, key) {
// Imitate "transparent" proxy
if (key === 'get') return;
throw new Error('observable');
}
}));
console.assert(proxy.test === true);
const sub = Object.create(proxy);
console.assert(sub.test === true);
