protected function Renderer::xssFilterAdminIfUnsafe

protected Renderer::xssFilterAdminIfUnsafe($string)

Applies a very permissive XSS/HTML filter for admin-only use.

Return value

\Drupal\Core\Render\Markup The escaped string wrapped in a Markup object. If the string is an instance of \Drupal\Component\Render\MarkupInterface, it won't be escaped again.
