As evidenced by T166735, these are missing from spec.
Hi @Gehel and @Pnorman - is this something that you can fix?
With some digging, either of us should be able to do it. The kartotherian comes bundled with its checks, so if @Pnorman wants to take responsibility for kartotherian, I can help him doing that, or I can dig myself.
Let's get this test created so that if maps stop working, someone is notified.

Moving to done - this has been merged.
