PopupTemplate Content strips HTML Data-* Attributes in ArcGSI JavaScript API 4.16

Working with the ArcGIS JavaScript API version 4.13 and was able to build popup templates that included data attributes to work with the Semantic UI library for their Tab module (https://semantic-ui.com/modules/tab.html). I recently upgraded to version 4.16 and now the template is broken. Upon examining the html when rendered it strips key data-attributes for tabs (data-tab) prevent it from working. Is there a way to force explicit content and prevent the template from being modified in version 4.16 or if this expected going forward?
