Describe the bug and add attachments

In Cart Rule.php when suming the price in $selected_products_reduction it takes into account the price_without_reduction so the value is greater than expected

// Discount (%) on the selection of products 
 if ((float) $this->reduction_percent && $this->reduction_product == -2) {
                $selected_products_reduction = 0;
                $selected_products = $this->checkProductRestrictionsFromCart($context->cart, true);
                if (is_array($selected_products)) {
                    foreach ($package_products as $product) {
                        if ((in_array($product['id_product'] . '-' . $product['id_product_attribute'], $selected_products)
                                || in_array($product['id_product'] . '-0', $selected_products))
                            && (($this->reduction_exclude_special && !$product['reduction_applies']) || !$this->reduction_exclude_special)) {
                            $price = $product['price'];
                            if ($use_tax) {
                                $price = $product['price_without_reduction'];
                            }

                            $selected_products_reduction += $price * $product['cart_quantity'];
                        }
                    }
                }
                $reduction_value += $selected_products_reduction * $this->reduction_percent / 100;
            }

Expected behavior

If you use $price = $product['price_with_reduction']; the sum is correct so the reduction percentage is calculated with respect the real price of the selected product/s

Steps to reproduce

Create a discount (cart rule) with selection of products. Use a Percentage discount and apply them to Selected products Some of the Selected products have a specific price discount. The discount is greater than expected because uses the price_without_reduction in the sum
