Should docker hub description auto-update from github readme.md?

I have a docker hub auto-build repository here:

https://registry.hub.docker.com/u/sdt4docker/raspberry-pi-cross-compiler/

which is attached to a github repo here:

https://github.com/sdt/docker-raspberry-pi-cross-compiler

I’m pretty sure that the docker hub description used to auto-update from the github readme.md, but that no longer seems to be the case. I pushed some changes to github a few days ago, and this triggered a new image build, but the description has not been updated.

I this right? Do I need to be manually copying the markdown from github to docker hub?

I had the same issue with some of my repos, so I updated them manually. However, please fix this!

I have the same issue since 2 weeks. It worked on some other repositories before, so this is definitly a bug that should be fixed.
It would also be great if you could support inline links in markdown [my internal link](#Header of subsection)
