A bug was reported where sidebar section headers appear bold when in the Admin area, even when the admin sidebar is disabled—this was unintended. The change was introduced in PR #26801 to visually distinguish the admin sidebar, but it incorrectly affected the regular sidebar too. bryce confirmed the change was intentional for admin distinction, and kris.kotlarek acknowledged the issue and fixed it in PR #26993. Moin first highlighted the unintended side effect, and AquaL1te originally reported the issue with screenshots. Separately, JammyDodger split off a related issue about category banners into its own topic.
