Valid attribute on methods break when read via ReflectionFunction

[nicolas-grekas]

Description

The following code:

#[Attribute(Attribute::TARGET_METHOD)]
class A
{
}

class B
{
    #[A]
    public function m()
    {
    }
}

$a = new B();
$c = [$a, 'm'];
$r = new ReflectionFunction($c(...));
var_dump($r->getAttributes()[0]->newInstance());

Resulted in this output:

Fatal error: Uncaught Error: Attribute "A" cannot target function (allowed targets: method)

But I expected this output instead:

object(A)#5 (0) {
}

The regression has been caused by #8424. @iluuu1994, any ideas on what to do?

Not off the top of my head. I can look into it next week (I'm on vacation this week).
