I'm playing a campaign as Milan with the aim to form Italy. I have secured myself as the HRE Emperor. However I think I remember reading somewhere that once I form Italy, I am removed as the emperor. Now I cant seem to find where I saw that, but I think it would have been to do with the fact that the capital gets changed to Rome when I form Italy, and since Rome isn't in the HRE, that's why I would get removed as Emperor. But if I add Rome to the HRE through prov decision before I form Italy, will I still stay the emperor once I form?
