JS Proxy Object cannot proxy function properties

// JS Proxy Qt issue
// "name" property is always empty and "toString" returns function not "hello world3".

// This is the simple object that we are attempting to proxy.
const testTarget = {
  "name": "hello world",
  "test": "hello world2",
  "toString": "hello world3",
}

// This takes some target JS object and wraps it in a Proxy.
// This Proxy is a simple passthrough proxy so should be invisible when used.
function wrapInProxy(targetObject) {
  const result = new Proxy(targetObject, {
    get(target, prop, receiver) {
      const value = target[prop];

      // This is required to call a function property with the correct "this".
      if (value instanceof Function) {
        return function (...args) {
          return value.apply(this === receiver ? target : this, args);
        };
      }
      return value;
    },
  });
  return result;
}

// Create our wrapped target object
let wrapped = wrapInProxy(testTarget, {})

// Incorrect -> TypeError: Type error
console.log("wrapped:", wrapped)

// Incorrect should be "hello world" but is "".
console.log("wrapped.name:", wrapped.name)
console.log("wrapped['name']:", wrapped["name"])

// Correct "hello world2".
console.log("wrapped.test:", wrapped.test)
console.log("wrapped['test']:", wrapped["test"])

// Incorrect gives "function toString() { [native code] }" instead of "hello world3"
console.log("wrapped.toString:", wrapped.toString)
console.log("wrapped['toString']:", wrapped["toString"])
