Comment:

 Given the CSS in [https://github.com/WordPress/wordpress-develop/pull/1602
 GB1602] only affects the legacy widget preview iframe and that nobody was
 able to find any issues with it, I think this is good to go for 5.9 as a
 fix for the problem.

 While the rules look like a sledgehammer the fact they only apply to the
 iframes in the widgets editor makes them less impactful than introducing
 logic in how `wp_footer` and enqueueing work.

 The rules to hide any extra content are really overwhelming, but I guess
 that's what you have to do to cover all possibilities.
