We've been able to toggle visibility of gists since 2014 (https://github.com/blog/1837-change-the-visibility-of-your-gists), but I just noticed that I can no longer make public gists private. That is, when I edit private gists I still see the "Make Public" button, but not the other way round — there's only a "Delete" button when I edit public gists; the "Make Secret" which should be next to it (as shown in the screencast in the linked blog post) is nowhere to be found. I made a screenshot and a screencast demonstrating the issue, both of which are attached. Could you please confirm this issue? Was this an intentional change, and why? Thank you for your attention.
