The "form-element-label--form-id--[form-id].html.twig" suggestion does not work

In the current version, the suggestion for form-element--form-id--[form-id].html.twig does not work.
There is a typo in the theme sugestion for label element.

When I change the line (33) $suggestions[] = 'form_element_label__form-id__' . $variables['element']['#form_id']; to $suggestions[] = 'form_element_label__form_id__' . $variables['element']['#form_id']; it works.

I have included a patch to fix the problem.
