If you try to preview an edit in the Wikitext editor, no preview is displayed (on en.wiki). Unlike Bug 72521, no Javascript error is thrown. It may or may not be related.

Looks like Section template got broken. To fix it: mw.mobileFrontend.require( 'Section' ).prototype.template = mw.mantle.template.compile( '{{#heading}}<h2><span id="{{anchor}}">{{{heading}}}</span><a href="#editor/{{id}}" data-section="{{id}}" class="edit-page">{{editLabel}}</a></h2>{{/heading}}<div>{{{content}}}</div>', 'hogan' )
