I almost think since custom menus are so popular it would be nice to have more options built into the header that can be changed in settings and would be checked against with updates. The customer headers I am seeing people build are all pretty similar.
Yeah, me too. My after header includes a menu that ties the forum into the rest of the website.
I might have a fix for this. I ran into the issue a week or two ago and wrote up some CSS that appears to fix it. I’d like to do a little more testing for bad side effects before I post it.
I am pretty sure something changed in core Discourse recently that led to the problem since I definitely remember a time when it wasn’t happening. Unfortunately, this type of thing happens with add-ons. The Discourse team can’t be expected to test every change against every customization that’s out there.

You can try this fix out on your sites by adding this CSS to your customization:
