Duplicate injections after rendering methods

[Gerych1984]

When using custom injectors that allow the user to add links/meta tags, when multiple render* methods are called, subsequent calls to getLinkTags/getMetaTags are also duplicated. For example:

public function index(SomeLinkTagsInjectionInterface $injection): ResponseInterface 
{
        $injection->addSomeLink('href', 'rel');
        $content = $this->viewRenderer->renderPartialAsString('index');

        return $this->render($content);
}

As result link tag rendered twice in layout head
