It seems like $this->mergeRaw($flatten) of type array is incompatible with the declared type Spiral\Stempler\Node\HTML\list of property $nodes.

            if (

                && isset($result[\count($result) - 1])
                && $result[\count($result) - 1] instanceof Raw

                $result[\count($result) - 1]->content .= $node->content;
