Closes #35652

Tests are not useful here since Jest seems to get in the way. You can validate manually in the Browser console though with class Foo { static name = {} } and

{
  const x = [];

  const cursor = () => {
    return new Proxy(() => x, { get() { return cursor(); }});
  };

  cursor().name + "() {}"
}
