Comment (by gziolo):

 It's very likely that both plugins don't use `register_block_type` with
 `block.json` that defines `editorScript` or `script`. It's the regular
 path when `register_block_script_handle` gets called. I can at least see
 that it's the case for Syntax-highlighting Code Blocks. Many plugins still
 manually enqueue the script that registers the block on the client.
