php shuffle doesn't work in smarty v5 #1096

Hello,

Hereafter my sample

<!doctype html>
<html>       
    <body>     
        {$tab = array('A', 'B', 'C', 'D', 'E')}
        <p>Before shuffle: {$tab|print_r}</p>
        {$res = $tab|shuffle}
        <p>After shuffle: {$tab|print_r}</p>

        <p>Before adnShuffle: {$tab|print_r}</p>
        {$new = $tab|adnShuffle}
        <p>After adnShuffle: {$new|print_r}</p>
    </body>
</html>

My result with smarty v5

Before shuffle: Array ( [0] => A [1] => B [2] => C [3] => D [4] => E ) 1

After shuffle: Array ( [0] => A [1] => B [2] => C [3] => D [4] => E ) 1

Before adnShuffle: Array ( [0] => A [1] => B [2] => C [3] => D [4] => E ) 1

After adnShuffle: Array ( [0] => B [1] => D [2] => E [3] => C [4] => A ) 1

It seems that the $tab variable is not modified after calling the php function shuffle
If I do a custom modifier, it works

function smarty_modifier_adnShuffle($iTab)
{
	shuffle($iTab);
	$new = array();
	foreach($iTab as $e) {
		$new[] = $e;
	}
	return $new;
}

Maybe because the shuffle parameter is a reference pointer?
