5.9.1 introduced bug of numerious <style>. wp-container-xxxxx etc</style> in html

In 5.9.0 this does not happen, however in 5.9.1 a bazillion <style>. wp-container-xxxxx ...</style> in the html. With each refresh more are added. Logged in or not logged in. With zero plugins.

It's Genesis framework. I have just checked with the 2022 theme and this bug is not there but as soon as I change the active theme to the Genesis parent theme, it's there.

Hopefully WPEngine/StudioPress will correct this. In my child theme functions I've added the following to correct this:

//Fixes 5.9.1 bug in Genesis
remove_filter( 'render_block', 'wp_render_layout_support_flag', 10, 2 );

This doesn't affect my site at all.
