Comment (by domainsupport):

 Seeing as the issue has not yet been fixed in Gutenberg, what is the
 recommended method for preventing the issue for plugin developers? I have
 come up with this ... ?

 {{{#!php
 <?php
 add_action( 'wp_footer', 'wp_footer_proof_of_concept' );

 function wp_footer_proof_of_concept() {

 if (!(defined('REST_REQUEST') && REST_REQUEST)) {

 echo "Why is this being output on the Widgets screen?";

 }

 }
 }}}

 Please confirm.

 Oliver
