[8.4] Widening property hook's type for promoted property does not work

Description

The following code:

<?php

declare(strict_types=1);

class Foo
{
    public function __construct(
        public int $baz { set (int|string|stdClass $value) {
            if (is_int($value)) {
                $this->baz = $value;
            } else if ($value instanceof stdClass
                && property_exists($value, 'baz')
                && is_int($value->baz)
            ) {
                $this->baz = $value->baz;
            } else if (is_numeric($value)) {
                $this->baz = (int) $value;
            } else {
                throw new InvalidArgumentException('Invalid value');
            }
        } },
    ) {}
}

$obj = new stdClass();
$obj->baz = 123;

var_dump(new Foo($obj));

Resulted in this output:

Fatal error: Uncaught TypeError: Foo::__construct(): Argument #1 ($baz) must be of type int, stdClass given, called in /in/2mZY5 on line 29 and defined in /in/2mZY5:7
Stack trace:
#0 /in/2mZY5(29): Foo->__construct(Object(stdClass))
#1 {main}
  thrown in /in/2mZY5 on line 7

But I expect this to work instead, just like when property is not promoted.

Empieza reproduciendo el ejemplo de promoted property del issue y compáralo con el ejemplo de non-promoted property enlazado allí. Sigue dónde se comprueba el tipo del argumento del constructor y dónde el property hook gestiona la asignación; se considera terminado cuando el caso promoted acepta como se espera la entrada ampliada del hook y tiene una prueba de regresión.
