In this edit, a user at German Wikipedia complains that the feature is visible again when using the mobile skin (minerva), and I can confirm that this is actually the case. This became apparent after CSS code was removed from MediaWiki:Mobile.css which set display:none; for .read-more-container (the container which contained the tool output).
- Is this intentional, i.e. should the feature be enabled in mobile view in German Wikipedia?
- Has the feature been activated before the mis-configuration was deployed initially?
