Subject: [PATCH] Editor: Fix regression introduced with loading separate block
 assets

Related to [50836]. load-styles.php doesn't load the should_load_separate_core_block_assets function and that causes an error 500 - which in turn makes the dashboard appear unstyled.

Props aristath.
Fixes #53180.
