Container theming is broken

[mxhCodes]

Using the container theming is completely broken thanks to this template:
https://github.com/BurdaMagazinOrg/infinite-theme/blob/8.x-1.x/templates/containers/container.html.twig

This template should contain at least:
<div{{ attributes.addClass(classes) }}>{{ children }}</div>
See also https://api.drupal.org/api/drupal/core%21modules%21system%21templates%21container.html.twig/8.2.x

I doubt we just can add the div container again though, because anyone seems to live with it for longer, and adding it would break existing sites.

Yeah, I have same problem with using Views Infinite Scroll.
