Current behaviour

function hi($in): mixed {
    
    $x = $good ?? [];
    $x2 = [$bad1] ?? [];
    $x3 = hi([$bad2]) ?? [];
    $x4 = hi([$bad3]) ?? '';
    
    return $_REQUEST['a'];
}

Expected behaviour

It correctly handles $good by highlighting it as a probable issue. However, when the undefined variable is tucked within an array, it doesn't seem to care? Every $bad# variable should be highlighted.
