Does not work without .views-content

A click on the >Show more< button does not display more items from the view in a custom theme. It works in another theme.

I found it is necessary the DOM contains a <div class="view-content">...</div> for the AJAX callback can insert new view result items. Some template sets like in core/themes/stable/templates/views/ or core/themes/stable/templates/views does not contain this element and the button will be disfunctional.
