In Debian the theme comes from gtk, too:
https://packages.debian.org/sid/libgtk-3-common

However, there is no ubuntu-mono.

Regardless, it seems the issue lies in the way Debian is handling packaging, so I would file a bug upstream if I were you. If you indeed believe it to be a bug. Might be good to check in with the gtk maintainers first and see if they can provide some insight.
