Optional: If you think this functionality is important, I suggest adding a test
at the corresponding test suite, at 

https://cs.chromium.org/chromium/src/chrome/test/data/webui/settings/certific....

We don't currently have any "guest mode" tests that I am aware of, but we
probably should. I don't think we should necessarily do this in individual page
tests (but maybe we should). Filed crbug.com/719562 to track this.
