Currently, template description and params description are on a single line whereas it is sometimes clearer to view an help on several lines.
\n symbol works on documentation page : we see a line break. But it does not show on TemplateData visual editor and on VisualEditor. On fr.wp there is a CSS edit suggestion.
Is it possible to allow to insert line breaks with <br> markup or with \n character please ?
Exemple of utilisation : fr:template:Lien web
