This is a minor bug with the new hats, but searching “hat overlap” in Math Meta brings up no questions, so this one might as well be the question for this issue. Here is a new hat which has a shape such that it sticks out when too big:
Notice how the Telescope overlaps the “member”, “profile”, and “activity” icons/text in the user profile. What can be done about this error? It probably can be fixed with hat size restrictions, but that would depend on whether the mobile version of (Math) Stack Exchange has the same error. Please correct me and give me feedback!
