I'm not sure what to mark my question, about a bug in WordPress. I ended up submitting it to Trac, which was subsequently closed as a duplicate. It's a long-standing bug and it seems a complex enough problem that it might never be fixed.
So, any advice on what to mark it? I mean, it's ''resolved'' in the sense of these forums, but
in the sense of WordPress (the software).
