Do AI countries ever leave the HRE on their own?

[Mindel]

Has anyone ever seen an AI nation leave the HRE aside from scripted events?

I don't recall this ever happening in any of my games, and I'm wondering if it actually happens.

I'm pretty sure that once an AI enters the HRE it won't ever leave it. Only exception I can think of is if they won't accept Revoke the Privilegia.
