Hi everyone, When I use <article> <details close ><summary>This is a test</summary> <iframe width="100%" height="300px" frameborder="0" allowfullscreen src="https://framacarte.org/en/map/apparts_88475?scaleControl=false&miniMap=false&scrollWheelZoom=false&zoomControl=true&allowEdit=false&moreControl=true&searchControl=null&tilelayersControl=null&embedControl=null&datalayersControl=true&onLoadPanel=undefined&captionBar=false"></iframe><p><a href="https://framacarte.org/en/map/apparts_88475">See full screen</a></p> </details> The content of the iframe doesn't load when I expand the section. With <details open> it's works... Any work around ? Thanks
