Gin theme checkbox styles breaks Webform custom composite fields required

I have a similar issue, except I still don't understand why.
I don't use webform, it's a boolean field in a node, displayed by boolean_checkbox form widget, with display_label option to 1.

In my case, i can see debugging gin_theme_suggestions_input_alter() function that #error_no_message exists and is TRUE.

Reading #2643012: Add property to identify if checkbox/radio is in group of checkboxes/radios → , checkboxes group is can be tested thanks to #error_no_message key AND #weight. After few tests and reading \Drupal\Core\Render\Element\Checkboxes, it seems checking #weight is float is more relevant than #error_no_message... but not the solution either.

Here is an example of a form. I should have toggle checkbox for fields, but none is displayed :

• Publié (published status)
• My checkbox (a boolean field)
• Sidebar > Create new revision
• Sidebar > Menu settings > Provide a menu link
• Sidebar > Simple XML Sitemap > Regenerate all sitemaps after hitting Save
• Sidebar > URL alias > Generate automatic URL alias

Then checking #weight is not float to use template suggestion :

function gin_theme_suggestions_input_alter(array &$suggestions, array $variables) {
  if ($variables['element']['#type'] === 'checkbox') {
    // Way to identify if checkbox is in a checkboxes group
    // as Drupal doesn't provide one yet (see #2643012)
    if (!is_float($variables['element']['#weight'])) {
      $suggestions[] = 'input__checkbox__toggle';
    }
  }
}

Finally, removing condition to always use template suggestion :

function gin_theme_suggestions_input_alter(array &$suggestions, array $variables) {
  if ($variables['element']['#type'] === 'checkbox') {
    // Way to identify if checkbox is in a checkboxes group
    // as Drupal doesn't provide one yet (see #2643012)
//    if (!is_float($variables['element']['#weight'])) {
      $suggestions[] = 'input__checkbox__toggle';
//    }
  }
}

Closing as I can't reproduce these issues on the latest Drupal versions.
