Yes, you currently indeed need the sage-combinat patches for this feature.

Upgrading sage and updating the sage-combinat queue is not super
robust. If you don't have local modifications, I would recommend to
just nuke the sage-combinat branch, and reinstall it:
sage -b main
rm -rf <... SAGE_ROOT ...>/devel/sage-combinat
sage -combinat install
(please be careful with the rm -rf!)
Hope this helps!
Cheers,
Nicolas
