Missing progress library and css file

Hi, I have a problem with the progress bar with this theme. Try doing a views bulk operation (batch enable) with an entity, progress bar stuck in initializing.

The theme has a template "templates/misc/progress-bar.html.twig" that references to a library that not exists.

{{ attach_library('bootstrap_barrio/progress') }}

This library should have an associated CSS that is not in css folder. (progress.css?¿)

My solution:

1. Create a 'bootstrap_barrio/progress' library in 'bootstrap_barrio.libraries.yml:

progress:
  version: VERSION
  css:
    component:
      css/components/progress.css: { weight: -10 }

2. Copy the classy core theme 'progress.css' in 'css/components'

3. Modify 'templates/misc/progress-bar.html.twig' file with:

{{ attach_library('bootstrap_barrio/progress') }}
<div class="progress" data-drupal-progress>
  {% if label %}
    <div class="progress__label">{{ label }}</div>
  {% endif %}
  <div class="progress__track"><div class="progress__bar" style="width: {{ percent }}%"></div></div>
  <div class="progress__percentage">{{ percent }}%</div>
  <div class="progress__description">{{ message }}</div>
</div>
