Description

When using types on the elements of an Iterator, then the IDE detects the wrong types while iterating via foreach.

The variable "$item" in the source code is of type "Model" and the IDE should suggest the properties of "Model". But it thinks "$item" is of type \TestIterator and suggests methods and properties of the \TestIterator type.

Run code completion on $item within the foreach to reproduce this issue.

class Model
{
    public $name = "test";
}

class TestIterator extends \ArrayIterator
{
    public function __construct(\Model ...$items)
    {
        parent::__construct($items);
    }

    public function current(): \Model
    {
        return parent::current();
    }

    public function offsetGet($offset): \Model
    {
        return parent::offsetGet($offset);
    }

}

$iterator = new \TestIterator(new Model(), new Model());
foreach ($iterator as $item)
{
   # run code completion on $item to reproduce issue
    echo $item;
}
