In WP trunk at the moment, since

Block Editor: Updated the WordPress packages to include Gutenberg 15.1.0 changes.

 - Add the right stylesheets to support iframed block editors.

Hi @kebbet, I am working on triaging the 6.2 project board. Now that #47824 has been merged, this issue can be closed, right?

Just to confirm, WP trunk does not display the fatal error from before, great work on this!
