https://github.com/nextcloud/server/issues/36460#issue-1564866420 explains the
problem. I won't duplicate the explanation because it's solely one click away
and is reliant upon Markdown, which this does not appear to support.

https://github.com/nextcloud/server/issues/36460#issuecomment-1419952140 states
that somewhere in bugzilla.opensuse.org should be the correct place for this
report.

However, please note that I had no more idea than that of where to file this
report, per https://unix.stackexchange.com/a/735651/386242. Selecting the
correct component is significantly less intuitive than redhat.bugzilla.org's
organization (there, components are packages).
