8.3 - cannot set finality and visibility for method from trait at the same time

Description

The following code:

<?php

trait SimpleTrait
{
    private function foo() {}
}

class TraitFixtureWithFinalAndProtected
{
    use SimpleTrait {
        foo as final protected;
    }
}

$rm = new ReflectionMethod(TraitFixtureWithFinalAndProtected::class, 'foo');
var_dump($rm->isFinal());
var_dump($rm->isPrivate());
var_dump($rm->isProtected());
var_dump($rm->isPublic());

Resulted in this output:

bool(false)
bool(true)
bool(false)
bool(false)

But I expected this output instead:

bool(true)
bool(false)
bool(true)
bool(false)

Looks like as final protected is completely ignored, does not change the method but does not throw an error either.

Inizia eseguendo il reproducer fornito per PHP 8.3 e confronta i flag di ReflectionMethod con l’output atteso. Segui il percorso di aliasing dei metodi dei trait responsabile di as final protected, quindi aggiungi un test di regressione che dimostri che entrambi i modificatori vengono applicati e conferma la visibilità e la finalità riflesse.
