Comment (by pkostadinov):

 Also seems to be related to this:

 https://developer.wordpress.org/reference/hooks/should_load_separate_core_block_assets/

 The name of the filter makes it sound like it only affect Core blocks, bit
 this seems to affect custom blocks assets as well.

 When I did a `__return_true`, this fixed my issue.

 I don't understand why this filter exists in the first place, and why the
 default is false - the default should always be to not load CSS that you
 are not using on the page, aka true.
