 We use a custom solution for adding footnotes to posts. All of our posts
 with footnotes became uneditable after WP's own implementation for
 footnotes was introduced. When trying to edit a post with "our" footnotes,
 the editor throws a JS error "i.map is not a function" for this line in
 core-data.min.js
 {{{
 i = t.footnotes ? JSON.parse(t.footnotes) : [];
 if (i.map((e => e.id)).join('') === r.join('')) return n;
 }}}
 Posts containing footnotes do not save or update anymore. We believe this
 is because WP footnotes are saved to a public, unprefixed meta field
 "footnotes" (see wp-includes\blocks\footnotes.php, 70), which conflicts
 with our own custom footnotes implementation, which already uses the exact
 same field name.
