Override container.html.twig template for a specific context
I just did this a month ago for the same reason:

/**
 * Implements hook_theme_suggestions_container_alter().
 */
function mytheme_theme_suggestions_container_alter(&amp;$suggestions, array $variables) {
  $element = $variables['element'];

  if (isset($element['#type']) &amp;&amp; $element['#type'] == 'view') {
    $suggestions[] = 'container__' . $element['#name'];
    $suggestions[] = 'container__' . $element['#name'] . '__' . $element['#display_id'];
  }

  if (isset($element['#type']) &amp;&amp; $element['#type'] == 'container' &amp;&amp; isset($element['children']['#type'])) {
    $suggestions[] = 'container__' . $element['children']['#type'];
  }
}


This will work for Views and general types. It is coming up blank because you need to handle it a little differently depending on whats being rendered.

Then in my twig file I am just doing:

{{ children }}

because I didn't want wrapping divs.
