I tried to hide the current revision of https://commons.wikimedia.beta.wmflabs.org/wiki/File:Begusarai.jpg to make it revert to the originally uploaded file. But "change visibility" is not linked for the current file version.
I had to revert the file first (so the current file version becomes an older version) before I could remove the offending file version. And now we're stuck with 2 revisions in the file history: the original upload and my revert, which again I can't get rid of because the revert is the current version.
In the end, I had to delete all revisions and restore only the original upload. This is counter intuitive.
Feature request: make "change visibility" linked for the current file version.
