Discussion Tools causes TemplateStyles to be empty in certain cases on pages without section headings. As a result, some templates don't appear correctly.
Splitting off from T270009.
Example affected page: https://nl.wikipedia.org/wiki/Overleg_gebruiker:Thomas~nlwiki
{F34121515}
Expected rendering should look like on this page: https://nl.wikipedia.org/wiki/Overleg_gebruiker:FQuist
