function ImageDimensionsTest::getImageTag

Render an image style element.

Function \Drupal\Core\Render\RendererInterface::render() alters the passed $variables array by adding a new key '#printed' => TRUE. This prevents next call to re-render the element. We wrap \Drupal\Core\Render\RendererInterface::render() in a helper protected method and pass each time a fresh array so that $variables won't get altered and the element is re-rendered each time.
