Just to make sure, when using the formerly blocked IP which is showing up as falsely blocked, when you go to the edit screen do you see a block notice?

Verified this problem exists on my own install.

This isn't a major issue though, as it's mostly just cosmetic and doesn't cause any loss in editing ability. Changing prioritisation and severity accordingly.

I've seen this issue before myself on the English Wikipedia. People were actively editing while appearing to be blocked. Then when I read the actual block message, I realised the block it was referring to had expired. You could even get it to display different block messages by browsing to different pages in the contributions.

I highly doubt this is leading to people being incorrectly blocked, but I can't actually verify that.

Just to clarify the issue is that if you are on an ACTUALLY blocked IP and view the contributions of a NOT actively blocked IP (but it used to be) it is showing up as blocked.
