Please get around to fixing all modules soon. It probably would’ve been better to make sure each module was covered before releasing this, as admins have to scramble with CSS to finish the race that Fandom stopped, but it’s too late for that. Here’s the modules that I’ve seen in need of restyling to match the new modules:
 * Insights (big one; it’s on every article page)
 * Popular blog posts
 * Pages I’m following
 * Custom JavaScript status
 * Hotspots (WikiActivity)
 * Community Corner (WikiActivity)
