Comment (by Bernhard Reiter):

 It seems like we basically need to backport
 https://github.com/WordPress/gutenberg/pull/32442, which was only merged
 briefly after the initial backport of custom block templates for pages
 (https://github.com/WordPress/wordpress-develop/pull/1267).

 I'll file a PR!
