Implements hook_library_info_alter().

The CSS files can be specified via the "edit_stylesheets" property in the .info.yml file:

quickedit_stylesheets:
-css / quickedit . css;

  if ($extension === 'quickedit' && isset($libraries['quickedit'])) {

    // First let the base theme modify the library, then the actual theme.
    $alter_library = function (&$library, $theme) use (&$alter_library) {

      /** @var \Drupal\Core\Extension\ThemeExtensionList $theme_list */
      $theme_list = \Drupal::service('extension.list.theme');
      if (!empty($theme) && ($theme_path = $theme_list
        ->getPath($theme))) {
        $info = $theme_list
          ->getExtensionInfo($theme);

        // Recurse to process base theme(s) first.
