Comment (by johnjamesjacoby):

 Hey friends. I found 2 plugins of mine that have broken styling due to
 this change.

 [https://github.com/stuttter/wp-multi-network WP Multi Network]
 [https://github.com/stuttter/wp-user-profiles WP User Profiles]

 For context, these plugins both implement their own versions of the "Add
 New" interface commonly associated with the Classic Editor experience. As
 such, they've manually implemented the DOM hierarchy from it, starting
 with `#poststuff` and finishing with `#postbox-container-1` and `#postbox-
 container-2` both of which contain their own registered meta-boxes for
 their own screens.

 I don't mind changing the ID to a class in my screens. I understand there
 are no guarantees that the admin-area DOM or accompanying styling will
 never change, so by copying it I'm assuming the responsibility to maintain
 my own copy.

 Since it is highly unlikely that my own screens will suffer the problem
 this ticket aims to solve, I may use both the ID and the class in my
 plugins to be prepared either way.

 Good luck with this one, everyone!
