Using Drupal 8 W3CSS Theme 8.x-1.17, I created a subtheme. The subtheme works fine, but on the settings page, the entire
#edit-favicon div is hidden;
style="display: none" has been added. I can't figure out why this is happening. However, on the parent theme, the favicon is being displayed. In
subtheme.info.yml, features and favicon are set to true.
settings: features: favicon: true
