I'm not sure where the best place to report this issue is, but when visiting https://app.pr-724-6b242e.sandboxes.opencraft.hosting/discussions/course-v1:openedx+123+2023/posts/66879d5d57bfb4002db05e09 with a small window I noticed a visual bug

I remove the dark mode configuration to load only the Paragon light theme and avoid the reported issue.
