I always edit when I'm registered, so I can't verify if it ever happens to anon editors. Irregardless, I think you've found the cause - the "cache" explanation sounds right.

I'll wait a bit to see if I can get a good screenshot before filing a report. I want to capture the little error message that pops out and, if I'm lucky, the category icons moving into the article.
