Clicking "Notifications" icon on GitHub Gist leads to 404

[PythonCoderAS]

If I click the notification bell on any GitHub Gist webpage, such as https://gist.github.com/, I go to a 404 since the link is https://gist.github.com/notifications.

Ah! Yes. I wanted to report this as well... I cannot see a repo for "gist" under github.com/github so I was wondering where is best to report it. It's slightly annoying, as I see a blue dot and I guess it is picking up the Notifications status from the main GitHub domain, but there's no notification page for gist.github.
