AEM 6.3, CoralUI slider in dialog: Cannot read property 'contains' of null If I try to add one of the sliders (to my component dialog) documented on this page: https://docs.adobe.com/docs/en/aem/6-3/develop/ref/coral-ui/coralui3/Coral.Slider.html, I get the following error:I think It has something to do with me trying to make it work in the template of a CoralUI.Multifield. If I try the following it works:$wrapper.append("<coral-slider step=\"2\" min=\"10\" max=\"20\" value=\"14\"></coral-slider>");This does not work:var rangedSlider = new Coral.RangedSlider();rangedSlider.set({ min: 0, max: 50, step: 2, startValue: 10, endValue: 20, tooltips: true, id: 'rangedSlider'});multifield.template.content.appendChild(rangedSlider);I had no issues with other CoralUI components added using the template (for example a 'CoralUI.Select'), all of them are working fine in my dialog. All help is appreciated!
