In top right corner of https://it.wikivoyage.org/wiki/Firenze can be seen:

• GPX icon
• Map icon
• Coords

These three items are stored inside this HTML block: <div class="mw-indicators mw-body-content">...</div>

In https://it.m.wikivoyage.org/wiki/Firenze the above mentioned items are not visible because the div-block is missing and class mw-indicators (or the equivalent mw-mf-indicators) is not defined, so when I use the HTML tag <indicator> (e.g. in https://it.wikivoyage.org/wiki/Template:Indicatore_GPX) the relevant indicators are not properly rendered.
