No marker via short url

I am not sure if this is the right place to post it, but I just want to make this little bug report regarding the map interface on https://www.openstreetmap.org :
When I share a location I can add a marker.
This works if I use the long URL.
When I switch to the short url and try it, the marker does not appear.

That sounds like something that could be logged at https://github.com/openstreetmap/openstreetmap-website/issues, but I’d check to make sure that it’s not logged already before creating a new issue (it does sound vaguely familiar).
