Gist preview uses incorrect nbviewer link format

I have a gist with jupyter notebook which uses an advanced widget which apparently isn’t supported on github directly. Instead, there’s a link to online nbviewer in top right:

However, it doesn’t work because it uses this incorrect url format:
https://nbviewer.ipython.org/github/<username>/<gist_ID>/blob/<commit_ID>/<filename>.ipynb

A correct one is either
https://nbviewer.ipython.org/urls/gist.github.com/<username>/<gist_ID>/raw/<commit_ID>/<filename>.ipynb (example)
or
https://nbviewer.ipython.org/gist/<username>/<gist_ID>

Btw limiting to 2 links for new user post isn’t very helpful when reporting a bug…

:wave: Welcome!

Thanks for the report! I’ve added your comment to the internal tracking issue and I’ll do my best to report back when I have an update.
