Inspecting the html:
<div class="ve-ui-mwNoticesPopupTool-items"><div class="ve-ui-mwNoticesPopupTool-item"><div class="mw-editnotice mw-editnotice-namespace mw-editnotice-0"><div id="editnotice-ns-0"></div> </div></div><div class="ve-ui-mwNoticesPopupTool-item"><p>You are editing a translatable page. Editing these in this editor is not yet officially supported.</p></div></div>
Possibly something to do about my local wiki setup about interface messages.
