Cool bug (potential WP core bug?) where meta with multiple rows registered as "single" prevents REST update.

Reproduction Steps

  1. Clone these files into a plugin directory
  2. Activate plugin (will populate several postmeta table rows about most recent posts)
  3. Open that post in the editor
  4. See the textbox in the Publish Status panel with label "Edit me:"
  5. Put any string into that input
  6. Try to save
  7. Encounter error Updating failed. Could not update the meta value of example_post_meta in database.

$table = [ [ ' file', 'function' ], [ '---------', '--------' ] ];
