This is how spec selector is implemented.

public function selector(\Closure $closure)
{
    $this->selector = new Selector();

    call_user_func($closure, $this->selector);

    $this->header(function () {
        return $this->renderSelector();
    });

    return $this;
}

I saw that, and imho the problem is, that header is overwritten, whilst logically it should be amended.
