Moin reports that category badges are missing from the group permissions page and user summary page, noting that this is a change from previous behavior where category names were missing but icons were present. Moin also observes that the badges are missing from oneboxes linking to other posts. Moin provides additional examples of where the badges have disappeared. RGJ suggests that the change does not appear intentional and that adding --style-square to the classes brings the badges back. Moin expresses hope that the badges will be added again soon, as they find them helpful for quick identification. awesomerobot acknowledges the reports and provides links to pull requests that will fix the issues on 404 pages, oneboxes, the user summary page, and the group permissions list.

I also noticed that the badge is no longer shown on oneboxes linking to other posts in the forum:
