As it was guessed by @Wiktor the issue was in setting proper headers. I was almost there, setting wrong headers.

Right headers are obviously: "text/html" (not "plain/text", it recognizes it just as a text in this case)

    $uploadResponse = new Response();
    $uploadResponse->headers->set('Content-type', 'text/html');

    $content = "";

    $uploadResponse->setContent($content);
