ReflectionFunction::isDeprecated() returns incorrect results for closures created from magic __call()

[TimWolla]

Description

The following code:

<?php

class Foo {
    #[Deprecated("xyzzy")]
    public function __call(string $name, array $args) {
    }
}

$foo = new Foo;
$closure = Closure::fromCallable([$foo, 'test']);
$closure2 = $foo->test(...);

$rc = new ReflectionFunction($closure);
var_dump($rc->getAttributes());
var_dump($rc->isDeprecated());

$rc = new ReflectionFunction($closure2);
var_dump($rc->getAttributes());
var_dump($rc->isDeprecated());

$closure();
$closure2();

Resulted in this output:

array(0) {
}
bool(false)
array(0) {
}
bool(false)

Deprecated: Method Foo::__call() is deprecated, xyzzy in /in/PZ4f2 on line 21

Deprecated: Method Foo::__call() is deprecated, xyzzy in /in/PZ4f2 on line 22

But I expected this output instead:

array(1) {
  [0]=>
  object(ReflectionAttribute)#5 (1) {
    ["name"]=>
    string(10) "Deprecated"
  }
}
bool(true)
array(1) {
  [0]=>
  object(ReflectionAttribute)#4 (1) {
    ["name"]=>
    string(10) "Deprecated"
  }
}
bool(true)

Deprecated: Method Foo::__call() is deprecated, xyzzy in /in/PZ4f2 on line 21
