How to test

• Add a snippet like <p id="hds-cookie-consent-full-page">Keksiasetukset vaativat javascript tuen toimiakseen.</p> to page, for example to paragraph--text.html.twig so that you can see the code on the page.
• Check that the cookie banner code (cookie-container.html.twig) has settingsPageSelector: '#hds-cookie-consent-full-page', set up.
• Verify that cookie banner renders on a page without the text paragraph (landing page) as a normal banner.
