This is a follow-up of bug 40098. A summary containing templates of a new section is now correctly formatted (the templates stay in their wikitext form) but the summary preview is still badly formatted: the templates are in their expanded form.
My test was at: https://fr.wikipedia.org/w/index.php?title=Utilisateur:Seb35/Potager&diff=83297187&oldid=48927364 but it’s not visible there since it’s only the preview which has to be corrected.
