Comment (by westonruter):

 I've just finished another pass at improving the preservation of classic
 theme CSS cascade when loading block styles on demand.

 The PR description has been fleshed out with all the details, but in
 short:

 1. Determining where to insert the styles hoisted from the footer has been
 made more robust by inserting placeholder inline styles. This simplifies
 the insertion logic since it doesn't have to hunt around for references
 for where styles should be inserted. It merely needs to replace the
 placeholders with the captured styles.
 2. The CSS cascade is now improved for inline styles which had been added
 to `wp-block-library`. Now when loading separate block styles, any such
 inline styles get added //after// any of the separate core block styles.

 Note: Do not have Gutenberg active when testing this, as the patch has not
 yet been applied to Gutenberg's forked version of
 `wp_enqueue_global_styles()`.

 Review and testing much appreciated: https://github.com/WordPress

 I really hope to get this into the next beta.
