Comment (by Bernhard Reiter):

 While working on https://github.com/WordPress/gutenberg/issues/44434
 (which is somewhat related), we've identified `WP_Theme_JSON_Resolver`'s
 caching of theme data as the problem. That caching happens early and
 sanitizes block-specific styling found in `theme.json` against the list of
 registered blocks. However, this can happen before all blocks are
 registered. As a consequence, some styling is scrapped.

 @cbravobernal has started working on a fix in https://github.com/WordPress
 /wordpress-develop/pull/3401.
